Many car owners have encountered this situation, that is, the headlights are fogging, but they do not know the cause of the fogging. Today I will tell you about the problem of headlights fogging.
The first reason is the weather. If the outside temperature is lower than the temperature inside the headlight, water vapor may form condensation inside the light housing. This condition is common in wet or rainy weather conditions.
The second is temperature changes. If the headlight assembly is exposed to sudden temperature changes, such as when you drive the car from a warm garage to a cold outdoor environment, water vapor may form condensation inside the light housing.
The third is a damaged seal. If the seal of the headlight assembly is damaged, moisture may get in. This may cause condensation to form inside the lamp housing.
The fourth is bulb replacement. If you have recently replaced the bulbs in your car headlights and did not use the dust cover correctly, moisture may get in and cause condensation to form inside the lamp housing.
His solution:
Turn on the headlights, switch between low beam and high beam every 15 minutes, and use the heat emitted by the bulb to bake the fog. Normally, it can be resolved in about half an hour.
So, will these little knowledge about car lights be helpful to you?
