    The seal is not good. Generally, the rear cover of a car headlight has a plastic ventilation duct from which the gases that expand in the lamp enter and exit. Sometimes, when some moisture enters the vent, a slight fogging can occur. It is recommended that you return to the 4S shop or auto repair shop to redo the seal!

    There is a water mist in the headlights of the car to eliminate the method as follows:1. Turn on the headlight switch and use the temperature generated by the headlight to evaporate the water mist.

    2. Stop in the sun for a few hours and use the temperature of the sun to evaporate the water mist.

    3. Open the dust cover behind the headlights and dry it with a hair dryer.

    If, after encountering water, it is found that the amount of water in the headlamp is obviously exceeded, forming a large amount of water mist, this situation can be judged that there is a problem with the sealing of the headlamp, such as the headlight cover or the back cover is damaged, or the sealing strip between the lamp cover and the back cover is a problem. At this time, the headlamp assembly can be removed first, carefully check whether the lampshade, back cover, and ventilation rubber pipe are damaged, and after confirming that there is no damage, it is recommended to separate the lampshade from the assembly, dry it in turn, and then reseal and install.

    In foggy days or high humidity environments, water droplets can easily form on the surface of car headlights, which not only affects the safety of driving, but also affects the aesthetics of the car's appearance. So, how to solve the problem of water beads in the fog of the headlamp grinding gear?

    First of all, a specialized car defogging spray can be used to solve the problem. These sprays form a protective film on the outer surface of the headlight, preventing water droplets from adhering to it and allowing the fog to dissipate quickly.

    Second, you can use a clean towel or soft cloth to wipe the surface of the headlight. When wiping, you can spray the surface of the headlight with water or detergent first, and then use a towel or soft cloth to gently wipe off the water droplets and mist.

    In addition, the outer surface of the headlights can be coated with a layer of car wax or glass water before driving. These coatings provide protection and anti-fogging, making it difficult for water droplets and fog to adhere to the headlight surface.

    Finally, it is very important to wash and maintain your car's headlights regularly. If there are smudges or dirt on the surface of the headlight, it is easy to form water droplets and fog. Regular cleaning and maintenance of your headlights with a dedicated car care product will keep them clean and bright at all times.

    In short, when encountering the problem of fogging and water droplets in the headlights, the above methods can be taken to solve it. It can not only improve driving safety, but also maintain the aesthetics of the car's appearance.

    As can be seen from the headlight structure, whether it is halogen headlights, xenon headlights or LED headlights, the inside of the headlights is almost sealed with sealing strips. When removing the back cover of the headlight, you will find that there is a layer of sealing strip on the headlight, which is the main measure to prevent water from entering the inside of the headlight of the car. In addition to this, there is a vent in the headlamp for ventilation inside the headlight, but there is also a dry cotton-like treatment at the vent to filter the air entering the headlight.

    From the above two measures, it is not difficult to see the real reason for the fogging inside the headlights. The first point is that the headlight back cover seal is damaged when it ages after long-term use or when disassembled. The second point is whether the dry cotton of the vents is still intact.

    When a car headlight is turned on, a lot of heat is generated, the air inside the headlight expands, and the air is exhausted through the headlight outlet. When the headlights stop working, the internal air cooling needs to be supplemented by outside air. At this time, the drying cotton of the air outlet plays a drying role, which can filter out the moisture in the air and ensure that the inside of the headlight is dry.

    However, in general, although water will enter the headlights, it will not collect in the headlights to form such a large fog, and the heat emitted is enough to expel moisture from the car without driving. The reason may be that the rear of the headlight is not tightly sealed and aging. If, likewise, after the headlights are turned off, moist air enters through the back cover instead of the vents, it turns out that after driving for a while, water mist is found inside the headlights, which is also related to the season and the temperature difference between day and night.

    The treatment of fog and water droplets in the headlights of the car is divided into two situations: turn on the headlights when there are fewer fog and water droplets in the headlights, and disassemble and dry them when the fog and water droplets in the car headlights are more.

    Here's how:

    1. There are fewer fog and water droplets in the headlights: the fog and water in the headlights can be turned on by turning on the headlights, and the heat generated by the headlights within 15 minutes can evaporate the fog or be discharged through the exhaust rubber pipe with the heat wave, which generally will not cause damage to the headlight circuit or bulb.

    2. There are many fog and water droplets in the headlights: in this case, it can be judged that there is a problem with the sealing of the headlights, such as the damage of the headlight cover or the back cover, or the sealing strip between the lamp cover and the back cover. At this time, the owner will not be allowed to continue to use the vehicle, go to the repair shop to ask the professional staff to remove the headlight assembly of the vehicle, and wipe the water mist inside the headlight.

    Then replace the sealing strip of the headlight assembly to avoid long-term use, resulting in water ingress inside the headlight assembly, damage to the connection line of the vehicle headlight, and even damage to other parts of the vehicle.

    After using it for a while, the mist will dissipate on its own.

    There is fog in the headlights, mostly because the temperature difference between the inside of the lights and the environment is relatively large, or it may be caused by the fact that the stagnant water is not thoroughly dried or discharged after the vehicle wading, car washing, and cleaning the engine compartment, but generally do not need to be ignored, and the fog will automatically dissipate after using a state for a period of time.

    If there is fog in the lamp, you don't need to dry it with a dryer, you can also get rid of the fog fifteen minutes after turning on the headlight, no matter what the headlight is, there is a ventilation rubber tube inside the headlamp and the outside is connected, when the light is lit and used, the bulb will produce a lot of heat, and the fog inside the headlamp will gradually evaporate, and the water vapor will flow out of the headlamp through the ventilation rubber tube.

    Although these problems will not affect the normal use of the light, how much time will affect the life of the headlight bulb.

    The headlights are the myopia glasses of the vehicle, if the eyes are short-sighted, how can you make the car bear? I firmly believe that most of the riders have encountered the situation of water in the headlights, so what should I do when the lights are fogged into the water. The owner's guide here is a detailed introduction to tips to solve the problem of water ingress in the headlights.

    Be the first to understand how water can get into the headlights.

    The overall sealing of the lampshade is indeed solved, but it does not mean that it is also a vacuum. Considering the convenience of maintenance in the future, it is common to leave a hand on the lampshade. The key to this point is from the perspective of heat exhaust, when the lights are turned on for a long time, a lot of heat will be formed, so it is necessary to ventilate the safety channel at this time to bring this heat out.

    Generally, the ventilation pipe is used to carry out the solution, and because of this ventilation pipe, the moisture in the air can enter the interior of the lamp according to this way and adhere to the surface of the lampshade, so it covers the lampshade with a layer of fog, and when it reaches a certain scale of operation, it will form water droplets to flow downward.

    How to deal with water ingress in the headlights.

    When the rainy season comes, the temperature is low, and when the lights are turned off for a long time, the temperature difference between the inside and outside natural environment is caused by the natural environment. In this case, the moisture in the air can easily enter the inside of the lamp through the ventilation duct or vent and adhere to the lamp shade. In this case, you only have to wait for the clouds to open and sunrise, and the lights are turned on again for a period of time, and the fog will automatically dissipate due to the increase in temperature, and there is no need to do other solutions.

    In addition, in the process of washing the car, you will also encounter the situation that the lights are foggy, so it is better to wait for the fog to dissipate.

    In addition to the heat transfer medium of the lamp temperature, is there any other way to deal with it by itself? Yes: No!

    Some friends have clear brain circuits and think of using drying equipment, hair dryers, etc. Excessive temperature can harm the lampshade, which can melt or crack at high temperatures due to the plastic raw materials used in the lampshade. The actual effect of the hair dryer on the air conditioner is biased, and most of the bells are blown for many times without any reflection.

    Some people will want to disassemble and assemble the lampshade themselves, but this is extremely not recommended here, because it is difficult to ensure the airtightness in the case of installation.

    When the headlights are often fogged, the buyer should check whether the airtightness of the lampshade is good, whether the lampshade itself is cracked, and whether the ventilation pipe or vent is blocked. Long-term fogging will greatly reduce the light transmittance of the lighting effect, and there is a very large safety risk in daily driving, so it is necessary to go to the automobile 4S shop or other professional auto repair shops as soon as possible to carry out maintenance.

    If there is fogging inside the exterior headlights, it can be divided into the following two situations according to the severity of the fogging:

    1.The water vapor inside the headlights condenses slightly, and no water droplets form on the surface of the headlights.

    2.The water vapor inside the headlamp is highly condensed, and large water droplets form on the surface of the headlight.

    First of all, let's talk about the reason for the slight condensation of water vapor in the inner fiber of the headlamp in the first case

    At present, the vehicle headlights of the existing structure are open ventilation and ruined structure, and the slight condensation of water vapor is a normal physical phenomenon. When the temperature drops, warm water vapor collects in the area inside the lamp where the temperature drops the fastest, condensing into water. The dissipation of condensate is related to environmental conditions such as temperature, humidity, and vehicle operating conditions.

    If the outside temperature is very high, the headlight fog will disappear quickly, so there is no need to replace the headlights. As long as the above situation is the case, as long as the humidity outside is not high, turning on the headlights for 30 minutes in a row can eliminate the fog inside.

    In the second case, the reasons for the high condensation of water vapor inside the headlamp are:

    First, check that all lampshades, ventilation elements, plugs, and lampholders are in the correct position; whether the air permeability of the breathable element is normal; Whether the lamp (housing, lampshade, etc.) has cracks. );whether there are installations or modifications related to headlight hail bridges; Whether there is a stranded wading section, etc.

    If the above external factors can be eliminated, the headlamp assembly needs to be replaced.
