How to Deal With the Water Mist of Car Headlights?

Jul. 29, 2020

I believe that many car owners have encountered water and fog in their headlights. What should I do if the headlights have water and fog? How to deal with it? LED front fog lamp supplier will share with you.

In fact, it is normal for car headlights to enter water and fog, and car owners don't need to worry too much. We all know that a lot of heat will be generated from the moment the headlights are lit until the headlights are used. There will be a venting rubber tube on the back cover of the headlight. The function of this rubber tube is to remove the heat generated after the headlight is turned on. However, the moisture in the air will enter the headlight through it and adhere to it. On the lampshade, with the accumulation of water vapor, water droplets formed and then flowed down the lampshade. Generally, this situation occurs when the temperature difference is relatively large, and this situation often occurs in winter and rainy seasons.

When encountering water and fog in car headlights, the best way is to turn on the headlights. Normally, after the car lights are turned on for a period of time, the fog will be discharged to the outside of the lights through the air duct along with the hot air, and will not cause damage to the headlights and circuits. If the car owner has a high-pressure air gun, or use a hair dryer, adjust it to the cold wind setting, and blow at the place where moisture is easy to accumulate in the engine compartment to speed up the air flow and remove the moisture.

A car owner asked, if this happens, can I use a dryer to bake the surface of the headlights? This is definitely not feasible, because most models of energy saving auto headlights lampshades are made of special plastic, if the baking temperature is too high, it will easily cause the headlights to age and yellow, or even crack directly when cold.

Note that these conditions are the treatment of the water mist in the headlights of the car. If there is a lot of water in the headlights, then there is basically a problem with the sealing of the headlights. The solution is to disassemble the headlight assembly, and then carefully check whether the internal components are damaged. If there is damage, then the headlight can only be replaced. It is worth mentioning that the 4s shop does not provide a separate replacement lampshade, the assembly must be replaced, so the price is more expensive. If the car owner thinks it is unnecessary, he can buy the lampshade of the same model online and then go to an outside auto repair shop to replace it. It is still difficult to replace it yourself.
