What kind of bulbs are in the foglights of the Lada Granta?

The relative simplicity of the Lada Granta’s design, including the liftback, allows for a number of preventive and repair work to be carried out outside the service center.

The rear lights include brake and side light bulbs (double-filament P21/5W), turn signal lamps (PY21W orange light), fog light (P21W) in the left lamp, and reverse light (P21W) in the right lamp.

The work is shown on the right lantern. We change the lamps in the left lamp in the same way

Replacement algorithm

• We turn off the engine, squeeze the handbrake;
• Open the back door;
• Depending on the model year, the sequence of actions differs. In the first generation (until 2015), unfasten the casing flap and provide free access to the back of the optics. In the second generation, remove the plastic latch, remove the lamps, unscrew the three nuts.

We bend the flap of the trunk upholstery.
We replace the reflector, lamps, and assemble the structure in the reverse order.

How to replace a lamp yourself

Replacing a fog lamp lamp itself is not a complicated operation, and if the lamp is replaced with one similar to the burnt one, practically no problems arise. Before starting work, for example, on a VAZ family car, it is advisable to drive the car into a pit, use a lift or raise the front part with a jack. This way it will be much more convenient to work, and less time will be spent.

Before changing the light bulb in the fog light, you should buy a similar one - in this case, it is better to give preference to well-known brands with a good reputation. For VAZs, the process of replacing a light bulb is as follows:

• the fog lamp power supply is found, the rubber protection moves away from the headlight;
• after this the block is carefully disconnected;
• the spring clips on the headlight reflector are unlocked;
• the light bulb is removed along with the wire;
• a new lamp is installed;
• The headlight is reassembled and checked.

It is enough to perform this manipulation once, so that the next time it takes only a few minutes to replace the light bulb in the fog light. The replacement process on other models depends on the design features of the foglights. On some cars, the PTFs are located in a block with the headlights - here you will have to disassemble the optics a little. An example of a replacement on a domestic Kalina in the video:

Types of lamps for PTF

If PTFs are installed by the automaker, then they use standard halogen lamps. Many motorists are not satisfied with them, which forces them to look for replacement options. There are currently three types of lamps on the market that can be used for fog lights:

• halogen;
• LED;
• gas-discharge, or xenon.

Before choosing the final replacement option, you should determine which bulbs are in the foglights. The main difficulty for most drivers is to correctly decide which lamps are best to install in fog lights - each of them has certain advantages and disadvantages.

Halogen

The most common type for fog lights, which has an affordable cost as its main advantage. Such elements ensure acceptable PTF efficiency in foggy conditions, and when properly configured, do not cause blinding oncoming drivers. Among the disadvantages of halogen lighting is a short working life, and replacing a bulb in a fog lamp is not always an easy task. In addition, the headlight becomes very hot, which, if it cools suddenly, can cause the glass to crack. If the power of the standard lamps for the driver is insufficient, when replacing the lamps in the fog lights with more powerful ones, there is a high risk of the control unit overheating and the headlights automatically turning off.

Typical signs of a lighting system malfunction

• lack of indication on the dashboard when the turn signals, high/low beam lever, and brake light are activated;
• frequent indication of the above indicators;
• the high/low beam lever does not activate the lamps;
• insufficient brightness of lamps and flashlight reflector.

The above signs indicate damage, deformation, or a break in the electrical circuit of the lighting system. To troubleshoot problems, you will need comprehensive diagnostics, identification of the breakdown, and subsequent replacement of elements. You can do this either independently or by contacting a service center for help from specialists.

I drove these myself for 2 years, installed fog breakers, and it got even better.

allseason supposedly installed yellow ones, I like the different lamps, there were some transitional models, my relatives had one, one Osram lamp, the other Philips, and I read something like this on the internet many times

I installed Allseason before the new year (available in the BZ) - I tested it on two excursions during the New Year holidays, both times with bad weather: the first - a snowstorm, the second - a half-damp track with ice and snow suspension. The result is good light.

I agree 100%. I installed these on Megan’s near-range H7, now I’ll install the same on the far-range H1))

Analysis of reviews from Lada Granta liftback owners

• Grant-Eject (https://www.drive2.ru/l/6512513/): the sedan's lamps are different from those of the liftback. In the first modification they are combined, in the liftback they are separate.
• Diyk: taillights often sweat on sedans, the problem has been eliminated in the liftback;
• Silica Gel: to quickly remove moisture, attach a moisture absorber for shoes to double-sided tape. It doesn't last long, but it's effective. Improving the sealing of the rear lights is an alternative option.
• Grant-Eject: insufficient fixation contributed to the flashlight falling out during movement.
• LADA Granta 2012 (https://www.zr.ru/content/articles/832528-lampy-primenyaemye-v-avtomobile-lada-granta/): the car is reliable, unpretentious, subject to a moderate driving style. Over a period of five years of operation, breakdowns are typical and characteristic.

Conclusion based on the results of the replacement The design and fixation of optical devices is not at all complicated. Every car owner can do the replacement; there is no need to contact a service center. Only as a last resort, when a global breakdown is identified or surgical intervention by a specialist is required. After reading the instructions provided, the owner knows exactly how to change the Granta liftback taillight with minimal time.

When to change lamps

Original light bulbs in Grant can last from 2 to 4 years. Replacement is necessary when signs appear:

• reducing beam power;
• a sharp increase in brightness;
• burnout of one of the threads.

The brightness of the Granta headlight is reduced due to burning of the filaments and smoke on the inner surface of the bulb. In this case, the flow of light is significantly reduced: the reflector cannot collect the required amount of light and direct it onto the road. The malfunction occurs at dusk, rain and on unlit sections of the road.

When falling into a hole, drivers notice a sharp increase in the light power in one of the headlights. This indicates a partial break of the filament and an excess of temperature at the filament point. Such a lamp needs to be replaced, as it is not capable of working for more than one day or even a few minutes.

If the thread breaks, the Grant optics go out and show no signs of operation until the burnt-out part is replaced.

When operating a Grant with a non-working lighting source, traffic police officers may issue a fine of 500 rubles.

Features of choice

For reasons of safety of drivers, passengers and pedestrians, the Traffic Rules and the Technical Regulations on the Safety of Wheeled Vehicles prohibit the operation of vehicles whose external lighting devices do not meet the design requirements of the vehicle.

Standard brake light bulbs for Lada Granta P21 5W. But, many modify and install their LED analogues 48LED SMD 3014 1157 BAY15d (BAZ15d). When purchasing LED brake warning lamps, many people wonder which is better to buy: white or red? Some generally argue that white LEDs cannot be installed in the stacks of headlights with a red filter.

In terms of contrast, the white LED, of course, is inferior to the red one, but everything is readable well without any other light overlays or shades.

But here it is worth noting that the fears associated with the operation of white LEDs paired with a red filter are not unfounded, especially with regard to some old flashlights with their red filters, as well as LED lamps, the color temperature of which can exceed 6000K, varying in shade into the obvious blue.

Reasons for the burnout of the brake light lamp on Grant

There can be many reasons for the frequent burnout of brake light bulbs on the Lada Granta, here are the most common ones:

1. Limited resource. Light bulbs from many manufacturers do not withstand constant use. Replacing standard lamps with cheap Chinese analogues makes itself felt.
2. Moisture getting inside the headlights. This occurs due to cracked or poorly fitting rubber seals. They are located between the body and the glass. This problem is easy to diagnose: the headlight regularly fogs up from the inside. This can also be verified by inspection.
3. Incorrect installation. Halogen headlights suffer if basic installation rules are not followed. For example, inexperienced car owners begin to install lamps with their bare hands, which is prohibited: the presence of greasy marks reduces their service life.
4. Incorrectly selected power. It is not recommended to install 100-watt lamps. You need to take less power, but increased brightness. This will significantly improve visibility and extend the life of the device.
5. Defective light bulbs. The low beam lamp often burns out when there are significant flaws made during assembly.
6. The flask tilts, the spiral moves off its axis. All this negatively affects performance.
7. Battery low. This happens when the unit gets old and begins to discharge quickly. Charging requires high currents, so the vehicle's on-board network suffers from overvoltage. This situation requires diagnosis by an experienced auto electrician.
8. Wiring problems. It can be damaged as a result of the carelessness of the car owner himself. You need to check the wiring if the car has a new owner. Understanding electrical wiring on your own is quite difficult.
9. Any malfunction of the on-board electrical network can cause failure of not only the light bulb, but also other electrical appliances.
10. Poor quality lamp. There are many unscrupulous manufacturers offering headlight bulbs with minimal working life.

If your rear brake lights stop working, you should not rush to extremes and run to an auto electrician; in most cases, the problem is solved by replacing the lamps.
