How to deal with water mist in car headlights?
Car headlights have water fog can be treated in this way: open the headlights to evaporate naturally, exposure to the sun, purge with high pressure water gun, replace the headlamp lamp shade, blow with a hair dryer, replace the headlamp seal, discharge dehumidifier, add cooling fan, replace the headlamp.
Turn on the headlight to evaporate naturally: when there are not too many water droplets or a small amount of water droplets, you can turn on the headlight for a while, and the temperature fog and water droplets inside will evaporate away.
Sun exposure: Placing the car in the sun for a few hours can also evaporate a small amount of water mist inside the car headlights.
Purge with high pressure water gun: If there is a high pressure air gun in the car, you can use the high pressure air gun to purge the engine compartment where moisture is easy to accumulate, accelerating the air flow to take away moisture.
Replace the headlamp cover: If there are cracks on the surface of the headlamp cover, water vapor will enter the headlamp through the cracks. At this time, it is necessary to check whether there are cracks on the surface of the headlamp. If there are cracks, you can go to a professional repair shop to repair or replace the lamp shade of the headlamp.
Blow with a hair dryer: Open the dust cover behind the headlamp, take out the headlamp, and dry the water mist with a hair dryer.
Replace the seal of the headlights: there is water fog in the headlights of the car, which may be caused by the aging of the seal, so that when it rains or when the car is washed, the water vapor enters the inside of the headlights and becomes fog. It is necessary to replace the seal of the headlamp in time to avoid water vapor entering again.
Dehumidifier: You can put a dehumidifier inside the lamp so that there is no more water vapor, but you need to remember to change it regularly.
Add cooling fan: If necessary, the owner can install a cooling fan in the headlamp position, the fan can discharge the hot air inside the headlamp to the outside, so that the air inside the headlamp can maintain circulation, no water vapor.
Replace the headlights: water vapor appears in the headlights, this may be because the headlights have been modified, the headlights after removal are not strictly installed, water is easy to penetrate from the gasket, it may also be because the location of the headlights collide, resulting in cracks or deformation, which also affects the tightness of the headlights, if the headlights have problems, to replace the headlights in time.
