Is it normal for headlights to be foggy?

Fog is a normal phenomenon in car headlights. The key is that the temperature of the headlights drops, the cold air outside enters the headlights, and the hot air inside the headlights touches the cold lampshade, so there will be a layer of fog. However, when the temperature of the range hood and the temperature inside the lamp reach a balance, the fog will not rise and will slowly dissipate.

This often happens in winter or rainy days with low temperature. In this weather, the temperature difference between inside and outside the headlights is quite large. In this case, friends don't have to worry, because it won't have anything to do with the car. Just turn on the headlights for a while and the fog will dissipate.

Little friends who don't understand, in this case, baking the headlights is easy to have a relationship with the headlights. Because the hood is basically made of plastic, if the baking temperature is high, it will burn the hood, which is not worth the candle.

In addition to the above situation, when the car enters the water, it will also fog the headlights, which cannot be treated as a common phenomenon. We should open the lampshade to dry, and then check the headlight surface for leakage or damage. If not, most of us basically replace the sealing strip and vent pipe on the headlight rear cover. If the situation is serious, we should send it to the repair shop and let the mechanic check what is wrong. Also, friends must be careful not to let the lights get into the water when washing the car.

In rainy or humid weather for several days, it is necessary to do a good job in detecting headlights. In rainy days, cars often wade. It is very important to check all parts of the car immediately after wading, and repair it immediately if there is any problem, otherwise it will cause big problems after a long time.
