The low beam or high beam has disappeared, the headlights do not light up: diagnostics

The low beam of both headlights does not come on. Opel Astra G-2002 The fuses are intact, the lamps too. What is the problem? Thank you! (Vadim)

Good afternoon, Vadim. Many motorists experience headlight malfunctions. There can indeed be many reasons why headlights do not work, and it is not a fact that they are related to fuses and the lamps themselves. Now we will try to advise you on how to solve this problem.

Peugeot 406 silver lion › Logbook › The left low beam headlight does not light up

This is the situation, I was driving during the day, since a light bulb burned out, well, I went and bought it, changed it - it doesn’t light, I went and bought another one - it doesn’t light up, well, I gave up and went home, in the evening I started looking, the fuse is ok, the bulbs are ok, I changed the fuses just in case In some places, I also made a test lamp, I throw it on the Akum terminals - it lights up, on 2 contacts of the lamp - no, the on/off switch clicks. On the headlight, the high beam/side lights/turn signal works as it should, there is no low current, I removed the terminal from the headlight - everything is fine... help, what should I do? I definitely changed the light bulb))

the situation is simple, after the accident there were the same problems with the new headlight =)) I already forced the seller to exchange the headlight for me... BUT, I came to the pyzheklub and there they started reading books, as it turned out, for the low beam there is a separate fuse for each of the headlights for 15 , it is located in the engine compartment fuse block (between the battery and the cup)

Why may one low beam headlight not light?

Knowing why such a malfunction can occur and how it can be eliminated is useful for every driver, because this can also happen during a long trip, when there are no service stations nearby. Let's try to deal with this problem in all possible ways.

Sometimes the abnormal operation of headlights lies in very unusual reasons. Thus, there is a known case when the owner of a Niva turned off the low beam after he dismantled the headlight cleaners, which had long ceased to function. As a result, for a long time he could not understand why the low beam on both headlights turned off. Only through experimentation did he manage to discover that for the headlights to work normally, the presence of any motor, be it left or right, is necessary. Ultimately, it was necessary to create an imitation of the presence of these elements by closing the contacts going to them.

Which bank deposits will be subject to 13 percent?

The following are subject to taxation:

  • ruble and foreign currency deposits in banks located in the Russian Federation;
  • investments in debt securities.

The total amount of all investments of an individual is considered.

The following are not subject to tax:

  • deposits in the amount not exceeding 1 million rubles;
  • deposits with a rate of 1% or less (provided that during the year the rate did not increase above 1%);
  • escrow accounts.

Do investments add up?

Yes, all deposits of an individual across all banks are summed up. The income received for the year is considered to be based on the value of all bank investments, so there is no point in breaking them up into small amounts of less than 1 million rubles and opening them in different banks.

This is precisely what was stated by the Head of Sberbank, German Gref, who warned against the need to split investments - this will not help avoid a new tax burden.

The tax office will sum up all investments registered in the name of a particular citizen, calculate the total income received for the year on all deposits, and then determine the amount of excess over the product of the key rate and 1 million rubles.

From what date is it entered?

After the statement of the President of the Russian Federation, many are interested in the question of when the changes will come into force and from what date the new tax will be collected. The implementation dates are determined in the new law.

The tax burden on bank investments will take effect in 2021.

Notifications of the need and amount to be paid will be sent to investors as early as 2022. When calculating, the key rate as of 01/01/2021 will be taken.

The right low beam headlight does not light up

The defect is well known to owners of VAZ cars, who sometimes encounter the problem even after purchasing a new vehicle. In this case, most often the headlight on the right side of the car does not light up. In turn, the head light source on the left suffers from a similar problem to a lesser extent.

What to do if the low beam does not light up? The car owner has two solutions - contact qualified specialists to fix the problem, or do the work yourself. When choosing the second option, you must have the necessary tools and knowledge of the car’s design, as well as the features of the electrical circuit. If the high beam lights up normally, but there are problems with the low beam, there may be several reasons:

Headlight device

The first thing that needs to be mentioned when talking about problems with light is the design of the front headlight unit itself.

As a rule, this element includes the following components:

  • front lamps;
  • rear light bulbs;
  • turn signals;
  • parking lights.


Design of the VAZ 2114 headlights
In addition, some configurations may have additionally installed fog lights.

There are also several reasons why out of this entire list only the low beam may fail, namely:

  • burnout of light bulbs;
  • oxidation of contacts on light bulb sockets or sockets;
  • electrical circuit break;
  • blown fuses;
  • broken off/on button.


Diagnostics and repair of VAZ 2114 headlights

As you can see, there are not many possible causes of the malfunction, and finding them if the diagnostics are carried out correctly will not be difficult.

The right low beam headlight does not light up

MB - mounting block (black box), located on the left under the hood, (relays and fuses are located in it) block Ш 9 on the MB from below (from the driver’s feet under the panel, all the blocks are across, there is one along 19 pins, at the narrowed end terminal No. 1, then on one side from No. 2 to No. 10, the other side from No. 11 to No. 19) contacts 15 and 17 have wire insulation colors - yellow and yellow/black. It’s better to check with a tester (for example, a headlight bulb with two wires, one end to ground, and the other to contacts 15 and 17, if there is voltage at these points, in the same way on the rear light blocks and on the lights themselves. Go for it.

The lamps on the sidebars should be 5 watts, since the issue has been resolved, well, for now you can drive, but I would advise restoring the FACTORY circuit for switching on the sidebars, just find where you have a problem with the left side. (especially if the electrician is a relative, although it may make sense to go to another electrician who will not say “this will suit a relative,” but will do it as it should be). 7.5 amperes before should be enough even for two circuits (left and right).

The fuse is broken

This is the second common reason why the low beam light of one of the car headlights does not light up. Let's look at how to fix it yourself:

  • the fuse box for electrical circuits must be opened;
  • if one of the fuses has blown, it needs to be identified (usually this is not difficult) using a diagram;
  • The faulty fuse must be replaced with a new one.
We recommend

“The oil light is on at idle: let’s look at the reasons” More details
Let’s clarify that if fuses on your car often burn out, you need to look for a breakdown in the wiring. Then, using a special device, it is necessary to ring the wires to determine where their integrity is compromised. If it is impossible to do this yourself, you need to contact an electrician who can find the cause of frequent breakdowns. In fact, this is a rather serious problem, in which repairs cannot be put off for a long time, since breakdowns in the wiring can lead to a short circuit and fire of the machine.

Headlights do not light - low beam does not work, diagnostics and repair

  1. First of all, if the headlight does not light, we check the light bulb itself; it even happens that by the time you discovered a malfunction of the head light, both low-beam lamps had already burned out. This almost never happens with high beam lamps, since they are used very little.
  2. One of the most common reasons for headlights not working is a melted fuse thread. However, on most modern cars the power supply circuits of the right and left headlights are not interconnected and are protected by separate fuses. Therefore, the failure of one fuse element leads to the failure of one headlight. This headlight malfunction can be diagnosed visually by opening the mounting block and inspecting the fuses responsible for the operation of the failed lighting element. In cases where access to the mounting block is difficult, you should find out which other circuits are protected by this fuse and check the operation of devices receiving power from these circuits. If these devices also do not work, in 99% of cases the assumption about a failed fuse turns out to be correct.
  3. If the assumption that the protective element has melted is not confirmed, it is necessary to check the head light relay. Typically, a relay failure will cause only one of the lighting systems to stop working.
  4. It is also necessary to check all the connectors of the electrical wires going to the headlight; perhaps, after the last repair, they simply forgot to put a connector on the headlight terminal and, accordingly, it will not burn as a result. This happens if not a single light bulb is on in the headlights.
  5. If the headlights still do not light up, then further search is carried out under the hood of the car. You should carefully inspect the existing wires and connections, move the terminals suitable for the headlights, and check the lighting lamps. Sometimes, due to a power surge in the on-board network, it happens that both lamps burn out at the same time. Also, due to water entering the engine compartment, they can oxidize and cease to perform the conductive function of the “chips” at the junctions of the wires.

Wiring

First of all, when the low beam stops working, check the reliability of the connections in all the blocks involved in the low beam electrical circuit. Their contacts often simply oxidize and after cleaning the problem is eliminated. Sometimes also due to vibration the connectors come loose and the circuit breaks. The contact groups need to be cleaned of oxides - a needle file or a school eraser is suitable for this. A nail file will also work (this tool will probably be found in any car lady’s purse).

Sometimes the light does not come on because the button that turns it on fails. There are contacts inside it, which, in turn, can also be damaged by corrosion. It is not difficult to verify that the starting device has failed - just disconnect the wires from it and short-circuit them. If this is the reason, then the light will come on. There is no point in repairing a button that has become unusable - it is easier to replace it with a new one.

The low beam is not on and the high beam is on on a VAZ 2112

Also involved in the operation of the electrical circuit of external lighting are: the external lighting switch, which is located in the cabin on the front panel; The headlight switch is located on the steering column; The low beam relay, the high beam relay and 4 fuses are located in the mounting block, and the high beam warning lamp is located on the instrument panel. When the high beams are turned on, all 4 filaments in the exterior lighting lamps should light up. If one or more threads of the headlight lamps do not light, then, without getting out of the car, check the integrity of the fuses located in the mounting block under numbers F2, F3, F12, F13. Fuse F2 protects the low beam filament in the left headlight, F3 protects the high beam filament in the left headlight, F12 protects the low beam filament in the right headlight, F13 protects the high beam filament in the right headlight and the high beam indicator lamp. Provided that the fuses are intact and their contacts are not oxidized, you will have to get out of the car, open the hood and check the serviceability of the corresponding lamps, those that do not light up.

If the fuses and lamps are intact and undamaged, then we check the two relays indicated on the electrical diagram as K4 and K5. Their possible malfunctions will be oxidation or burning of the contacts, which can be eliminated by cleaning them. If the relays completely fail, you will have to install serviceable ones instead. After making sure that all of the above devices are in working order, you will have to check the reliability of the connections in the blocks included in the electrical circuit of the headlights and the fastening of the headlights' ground wires. One ground fastener is located on the left, next to the battery on the air intake mount. Second from the right, in the place where the adsorber is located. If this does not help, you will have to remove the headlight switch and the exterior lighting switch one by one and check the condition of the contacts in them.

One of the high beam lamps has burned out

With such a malfunction, the high beam does not fail completely - as a rule, only one lamp turns off. Almost every car owner knows the solution to the problem in this case, but we will still remind you how to make a replacement:

  • Unscrew the bolts securing the rim of the faulty headlight
  • Turn the glass clockwise and pull the headlight out of the housing
  • Disconnect wires from contacts
  • Press the latch and carefully remove the light bulb

You can verify that the lamp is faulty by examining the filament (as is the case with ordinary household lamps). If the lamp is faulty, you need to purchase a new lamp and install it in place of the old one, without touching the glass with your hands. After that, reassemble everything in reverse order and make sure the high beam is working.

The low beam headlights don't come on, but the high beams do? Ways to solve the problem

A little subtlety:

The flask should be wiped with alcohol before installation, otherwise it will burn instantly. It is also not recommended to handle the bulb with unprotected hands: there is always some greasy and damp secretions on them, which can damage the light bulb. The best way to do this (replace the lighting) is with a dry cloth or rag.

By the way, if fuses blow with unenviable regularity, it means there is a breakdown somewhere in the wiring. Either wire the entire circuit yourself, or visit a professional electrician - problems with the wires can lead to all sorts of troubles, including a fire.

The right low beam headlight does not light up

Driving with one headlight at night is a violation, as it creates a danger to traffic. Clause 1.5 of the traffic rules. But if you took all precautions (emergency signal) and proceed to the place of parking or repair, then this is no longer a violation. You act accordingly. c clause 2.3.1. Traffic rules As a conclusion, the violation in this case is failure to act to eliminate the source of danger to traffic.

In theory, paragraph 2.3.1. The traffic rules allow you to move, taking precautions, only if OTHER malfunctions occur, indicated in the Basic Provisions. That is, the faults noted at the beginning of this paragraph do not allow you to move at all! This question is even included in the tickets (during the dispute they were even raised, albeit old ones): “When you can’t even move to the parking lot or repair site?”

The low beam of the right headlight does not light up

And here you no longer have to blame the quality and reliability of the parts belonging to this or that brand - it’s just that sooner or later all the parts get tired or they simply exhaust their service life. If one low-beam headlight does not light, it is best to contact an experienced auto electrician at a car service center, but this type of problem can be fixed almost easily on your own. Of course, if you have a little free time and basic knowledge about the operation of electrical circuits.

If your headlights are not on and your low beam lighting is not working, then driving at night with a faulty car is not only prohibited by traffic regulations, but also extremely dangerous. However, sometimes situations arise when the headlights go out during a trip. It is not always possible to spend the night in the car and finish the trip in the morning. We will tell you how to repair the exterior lighting of a car and how to get to the repair.

Let's sum it up

Taking into account the above information, it becomes clear that most malfunctions related to the external lighting of the car (low beam is gone, high beam is not on, low and high beam headlights are not on, etc.) are relatively easy to fix. The main thing is to find the cause of the breakdown and choose the right method to repair a particular malfunction.

We also recommend reading the article about which lamps are better, halogen or LED. From this article you will learn about the advantages and disadvantages of lamps of this type, as well as what features and nuances you should pay attention to when choosing a particular type of automobile lamps for headlights.

Finally, we note that only with a working headlight cleaning system, provided that the headlights are correctly adjusted and the car’s lighting equipment is fully functional, the driver receives safety and comfort. At the same time, the external lighting of the car allows the driver himself to navigate in the dark, and for other road users to detect the vehicle.

This means you should make sure your car's headlights and brake lights are working properly before every trip. If malfunctions are noticed, until the breakdown is eliminated, operating the car in the dark or in poor visibility conditions (if the brake lights are faulty, even during the day) is prohibited.

What to do if one low beam headlight does not light up

As you know, if one low beam headlight is not on, the fine can be up to 500 rubles. Of course, you can try to convince the traffic police inspector that you are just heading to the service center to solve the problem, but most likely he will refer to Article 12.20 of the Code of Administrative Offenses, which talks about preventive measures related to violation of the rules for the use of lighting devices on automatic telephone exchanges .

Almost every car owner is faced with a situation where the high beam headlights work, but the low beam does not turn on. Not only used cars suffer from this defect, but also cars that have just rolled off the production line. For example, new VAZs refuse to turn on the lights every other time, and owners of foreign cars often complain about this shortcoming.

Low beam on 2106: possible causes of malfunctions, replacing the bulb and fuse

The most common cause of headlight failure in any vehicle is a burned out bulb. However, sometimes other elements of electrical equipment also fail. Below we will look at the possible causes of low beam malfunction on a VAZ 2106 car and how to eliminate them.

  • If there is no voltage supplied to the relays and fuses, you should check the wiring section from switch No. 5 to terminal No. 86 on the relay, as well as the section from the switch to the external lighting switch No. 8. If the machine's wiring is normal, then the switch has failed.
  • If voltage is supplied to the fuses, then an open circuit must be looked for in the area from the block to the headlights. Often the breakdown is due to poor ground contact. In this case, you just need to clean the contact.

My headlight fuse keeps blowing after replacement.

Trying to find the source of a short in a circuit can be challenging.

A short circuit occurs when the power or main wire (carrying current to the loads in a circuit) finds a short path to a grounded surface. Most likely, a short circuit will cause a circuit fuse to blow or one or more light bulbs to burn out.

Short circuits can happen when:

  1. The insulation of the hot wire breaks and the wire touches the metal of the housing.
  2. The hot wire becomes pinched between the two pieces, cutting the insulation and creating a ground.
  3. The hot wire becomes disconnected from the component and dangles, touching the ground.
  4. The hot surface melts the insulation of the hot wire, allowing the bare wire to touch the grounded surface.

This general way to find closure may work for you:

  1. Connect a test light across the blown fuse or circuit breaker. If the indicator light is on, there is a short circuit in the circuit.
  2. Disconnect the socket, relay and switch one at a time.
  3. When the test light goes off, you have found the part of the circuit where the short circuit is located.

If necessary, consult your vehicle's repair manual to locate components and identify wires.

The right low beam headlight of VAZ 2106 does not light up

Such tuning is created by ordinary people, and the second one can quickly do the work with more compact units, but after it the right low-beam headlight of the VAZ 2106 does not light up. To restore a machine, you should first get an idea of ​​the structure and circuit of this unit. On the microcircuit, near the self-tapping screw, the leg is unsoldered. And in conclusion, the last piece of advice, if you want to keep it after this, then don’t even think about araservice.

And I personally don’t really like the one-and-a-half-bars, which are used for mounting shock absorbers, and the flanges are necessary for attaching the rear wheel hub and the brake shield using bolts. The basket is equipped with 18 petals and the driven shaft 3200 0206 has 4 springs. I didn't notice any wear on both center bushings.

If your headlights are not on and your low beam lighting is not working, then driving at night with a faulty car is not only prohibited by traffic regulations, but also extremely dangerous. However, sometimes situations arise when the headlights go out during a trip. It is not always possible to spend the night in the car and finish the trip in the morning. We will tell you how to repair the exterior lighting of a car and how to get to the repair.

Possible causes and diagnostics of the malfunction

  1. First of all, if the headlight does not light, we check the light bulb itself; it even happens that by the time you discovered a malfunction of the head light, both low-beam lamps had already burned out. This almost never happens with high beam lamps, since they are used very little.
  2. One of the most common reasons for headlights not working is a melted fuse thread. However, on most modern cars the power supply circuits of the right and left headlights are not interconnected and are protected by separate fuses. Therefore, the failure of one fuse element leads to the failure of one headlight. This headlight malfunction can be diagnosed visually by opening the mounting block and inspecting the fuses responsible for the operation of the failed lighting element. In cases where access to the mounting block is difficult, you should find out which other circuits are protected by this fuse and check the operation of devices receiving power from these circuits. If these devices also do not work, in 99% of cases the assumption about a failed fuse turns out to be correct.
  3. If the assumption that the protective element has melted is not confirmed, it is necessary to check the head light relay. Typically, a relay failure will cause only one of the lighting systems to stop working. Either the low or high beam disappears. You can verify the functionality of the light switch relay by carefully listening to the sounds that occur when you try to turn on the headlights. If short, loud clicks are heard from under the instrument panel when turned on, this indicates that the relay is working properly. The absence of a click confirms the assumption that the relay is faulty.
  4. It is also necessary to check all the connectors of the electrical wires going to the headlight; perhaps, after the last repair, they simply forgot to put a connector on the headlight terminal and, accordingly, it will not burn as a result. This happens if not a single light bulb is on in the headlights.
  5. If the headlights still do not light up, then further search is carried out under the hood of the car. You should carefully inspect the existing wires and connections, move the terminals suitable for the headlights, and check the lighting lamps. Sometimes, due to a power surge in the on-board network, it happens that both lamps burn out at the same time. Also, due to water entering the engine compartment, they can oxidize and cease to perform the conductive function of the “chips” at the junctions of the wires.

Methods for repairing headlights in the field

The above-described malfunctions are quite easily eliminated right on the road. No complex diagnostic or repair equipment is required. So, instead of a blown fuse, you can insert several cores from a stranded wire. In this case, one core is approximately capable of withstanding 1 ampere. The veins can be inserted directly into the socket or wrapped around the fuse. It is important that the contact surface is pressed tightly against the homemade fusible element.

A faulty relay can be replaced with a similar one used to switch on other high-voltage circuits. You can dismantle and use to replace a faulty headlight switch relay the element for switching on the power window circuit, heated seats, and additional equipment. In addition, many cars have a special backup socket with an unused relay. The connectors of almost all the elements in question in the car are similar to each other.

To turn on the headlights bypassing any faulty elements of the power circuit, you should use wires of sufficient cross-section and length. In this case, the ends of the wires are stripped of insulation and connected to a car socket designed for a portable lamp. The “cigarette lighter” can be used in a similar way. In this case, it is better to connect from the reverse side of the power point, connecting the wires directly to the terminals. The second ends of the wires are connected directly to the low beam lamp. It is important that only one headlight should be connected in this way. This is enough to get to your home or repair site while taking the necessary precautions. Connecting two powerful electrical consumers at once can lead to an overload of the power supply circuit of the cigarette lighter or socket, which often causes a fire in the car! You can read how to improve the headlights of your car here.

Checking for broken contact

If you are not sure if the thread is broken, you can check its integrity:

  1. Set the digital voltmeter (DMM) to the lowest value on the resistance scale.
  2. Turn on the digital multimeter and touch the test leads on each side of the lamp contacts.

If there is continuity, your indicator will beep or show zero resistance; otherwise, the display will show infinite resistance, overload, or no sound, depending on the specific meter configuration.

The following video shows how a blown fuse can affect one headlight.

Attention: proper handling of car headlight bulbs

When working with a light bulb, never touch its surface. Oil on the skin of your fingers, combined with the high operating temperature of the bulb, will shorten the life of the bulb or cause it to break down more quickly.

Car headlights - a guarantee of your safety

Safety behind the wheel plays an important role for every motorist.

In this regard, drivers should remember some factors that ensure their safety. However, the most important thing is that, while driving, you need to clearly see the road along which the car is moving. This is why driving lights are so important. They provide the driver with good visibility in cloudy weather or at night.

Today, the auto parts market offers several types of headlights.

All of them can be divided into several categories.

  1. Of course, something needs to be said about the fog lights. As the name suggests, fog lights are designed to provide additional illumination of the road during thick fog. Most cars come with a set of fog lights from the factory. Typically, this type of headlight is installed on the front bumper. However, to increase the illumination area, you can purchase an additional set of headlights yourself. Some car brands provide wide lighting angles initially.
  2. When traveling on unfamiliar roads, the driver must have good visibility in front of him. For this you need a powerful high beam. Here, car spotlights produced by some companies come to the driver's aid. But it is necessary to keep in mind that such headlights are not intended for city roads, since their light can blind other drivers. But for country roads this type of lighting will come in handy.
  3. On the one hand, we can talk about the uniqueness of high beam headlights. They are typically placed lower than off-road headlights. However, their purpose is to improve road illumination in addition to low-beam headlights. For natural reasons, their light is directed forward, unlike fog lights. Before using high beam headlights, you need to remember that its brightness can blind drivers of cars in front. Therefore, it is better to turn it on when the track is empty.
  4. An auxiliary lighting system offers several benefits. First of all, it's a great way to stand out. Also, auxiliary lights will help others easily spot your vehicle at night. And finally, they help the driver to navigate well in the dark.

There are other types of headlights on a car. For example, xenon headlights or high intensity discharge lamps. The most important thing is to have a proper headlight leveling and cleaning system to get the most out of your vehicle.

Troubleshooting non-working headlights

Using symptom-based diagnostics to check for headlight problems can speed up your repairs.

But remember that while lighting systems must adhere to the basic installation required by federal regulations, you will still find different configurations depending on the make and model of your vehicle. Therefore, always check your vehicle's repair manual to determine the correct wires, components, and operating mode when needed.

Using the simple strategies outlined in this guide, you can fix your headlights at home much faster with a few simple tools and save on repair costs.
