What to do if there is fog in the headlights, what to do if there is fog in the headlights of the ca

The back cover is opened with low beam and high beam, and then pointed, when the fog inside is almost dissolved, close the back cover, and then there will be no fog the next day, if the fog is in the middle of the headlights, it is estimated that it is water, and it is normal to have fog on the side.

Hello, there is fog in the headlight, which is generally caused by the poor sealing of the headlight, and only by replacing the headlight can this problem be solved.

If the headlights are foggy, it may be caused by poor sealing, and it is enough to redo the sealing treatment of the lower lights.

The headlights are foggy, this is because of air leakage, this is a quality problem, if it is within the warranty period, it can be claimed.

If there is fog, it means that it is caused by poor sealing, go to the after-sales service to re-seal or replace the headlights.

The fog in the headlights is generally caused by the aging of the sealing strip and the poor sealing effect, so it is recommended to re-seal it.

Hello, your situation is generally caused by the poor sealing of the headlights. It is recommended that you go to a repair shop or 4S shop to reseal.

Hello, generally the headlights are not well sealed, if you are a new car, go to the 4S shop to deal with it, and if you don't handle it well, you will be asked to replace the headlights.

This can be removed and resealed in the repair shop, it is a small problem, you don't need to care, I hope it can help you.

This is because the sealing of the headlights is not tight, if it is within the warranty period, you can go to the 4S store to make a claim and replace it free of charge.

This is generally due to long-term use, the sealing effect of the headlights is not very good, you can go to the 4S store to do a treatment.

Hello, this is caused by the headlight leaking and poor sealing, if you have a new car, you can ask for a change.

This is generally not well sealed.,If the shelf life is considered to go to 4s after resealing.。。

I want to ask, have you ever modified the headlights? If it has been modified, you need to check whether the sealing ring, including the back cover, is it installed in place? If it is not modified, and the vehicle is within the warranty period, you can go to the four S shop for warranty and replacement.

You seem to be in this situation mainly due to poor sealing of the headlights, and you need to go to the repair shop to check if there is a problem with the seal?

This is all caused by poor sealing. Need to enter the store to check whether it is a problem with the sealing ring?

The treatment method of headlight fogging: 1. The defogging method caused by physical phenomena: if the headlights are "fogging" caused by physical phenomena, the owner does not need to be anxious, as long as the headlights are turned on normally every day, the fog will dissipate in about a week; 2. Defogging method for fogging caused by water ingress:

Keep the engine idling first, then open the engine compartment cover, then unscrew the dust cover or dust cover, and continue to turn on the headlights for about 30 minutes, then use an air spray gun to increase the airflow speed in the lamp cover until the dehumidification and defogging are completed; At the same time, be sure to find the place where the seal is not tight, clean it and dry it, and then reseal it; 3. The method of defogging in a dry climate: turn on the headlights to dry the fog inside, then turn off the engine and turn off the headlights, and pour water on the parts that may preliminarily judge that there may be water seepage, such as the waterproof cover or waterproof cover, if there is fog in the headlights after a few minutes, then it can be judged that the water ingress caused by the poor sealing here, otherwise there is a problem with the bonding between the lampshade and the lamp base; Once it is found that there is damage or the adhesive is not good, it should be replaced or re-glued immediately.

The treatment of car fog is:

1.It may be that there is a problem with the heat dissipation ventilation duct, which causes the temperature inside and outside the headlight to be inconsistent, and fog will form inside the headlight. You can turn on the switch of the headlight, dry the fog with the heat of the headlight, and then go to a store in 4S to check the headlight ventilation duct.

2.It may be that before the headlight sealing strip of the car is aging, the water vapor enters the inside of the headlight when it rains or washes the car, and it becomes fog. Replace the headlight sealing strip in time to avoid water vapor re-entering.

3.If there is a crack in the surface of the headlamp shade, water vapor will enter the inside of the headlight through the crack. At this time, it is necessary to check whether there are cracks on the surface of the headlights, and repair or replace the headlamp covers.

Car headlight principle:

1.Whether it's a regular halogen headlight, an argon headlight, or a headlight with LED lights, there is a ventilation hose on the back cover.

2.At the moment when the headlights are lit and even during the use of the headlights, a large amount of good clear heat will be generated. The function of the snorkel is to exhaust the heat as much as possible from the headlights, so as to maintain the normal working temperature of the headlights and ensure the stable use of the headlights.

3.Moisture in the air enters the headlight through the snorkel and adheres to the lampshade. As the water vapor gathers, water droplets flow down the lampshade.

Many drivers have encountered fog in the headlights of their cars. The headlights at this time are like watery eyes, which makes people feel pity. What's going on?

How can you be wronged like this? Is it the poor sealing of the headlamp that causes water to enter the inside of the headlight, or is the lampshade damaged and the water vapor seeping into the inside of the headlamp?

As far as the overall structure of the headlights is concerned, whether it is a normal halogen headlight, a xenon headlight or a headlight with an LED light cluster, there is an exhaust hose on the back cover. The moment the headlights are lit, or even when the headlights are in use, a lot of heat is generated. The function of the snorkel is to exhaust the heat as much as possible from the headlights to maintain the normal working temperature of the headlights and ensure the stable use of the headlights.

This is the ventilation pipe, through which the moisture in the empty air enters the headlight and attaches to the lampshade. As water vapor accumulates, water droplets flow down the lampshade. This situation is mostly caused by large temperature differences, and it is most likely to occur in winter and rainy season.

In this case, the driver does not have to worry too much. After the headlights are turned on for a period of time, the fog will be discharged from the headlights through the snorkel with the hot air, and there will be no damage to the headlights and electrical circuits. In this case, the driver must not act rashly, such as do not bake the headlights, which is easy to damage the headlights, because the headlights are made of plastic, and the excess heat is easy to bake the lampshade, and most of this damage is irreversible.

In addition to weather changes, human factors can also turn the headlights into "tears", such as vehicle wading, car washing, and so on. When the vehicle wades in water, because the engine and exhaust system itself are relatively large heat sources, rainwater falling on it will form a large amount of water vapor in the hole, and part of the water vapor will enter the headlights along the snorkel.

Car washing is more straightforward. Some car owners like to use high-pressure water cannons to wash the engine compartment, watching the dirt and leaves being repelled one by one by the high-pressure water cannons in their hands, there is an indescribable sense of happiness. After washing, the water in the engine compartment was not treated when it was changed.

When the bonnet is closed, water vapor cannot be quickly released to the outside of the vehicle, and water vapor trapped in the engine compartment may enter the inside of the headlights.

When cleaning the engine compartment, we should wipe it with cotton silk or cloth, or use high-pressure air blowing, to try to avoid "moisture" of engine parts.

All of the above mentioned cases are relatively minor water ingress into the lamp. But if you have enough water in your headlights to raise fish, you need to take it apart, open the lampshade, and after drying, check the surface of the headlights for damage and possible leaks. If no abnormalities are found, we generally recommend replacing the seals and vents on the back cover of the headlights.

During the winter and rainy seasons, it is best for car owners to get into the habit of checking their headlights regularly. For example, check the vehicle after wading into the water. Early detection and early remediation, timely elimination of faults in the embryonic stage, is the best choice for car maintenance.
