Q: How to solve the problem of water inside the headlight?

A: It's normal for the car headlights to have water fog inside. Under the illumination of the car lights, a temperature difference will form on the surface of the lampshade, which will cause condensation and mist. Generally speaking, the water mist will dissipate automatically after turning on the headlights for an hour, not affecting regular use. However, if the water mist still exists after an hour, you have to consider that the water may have entered the interior of the headlights. In this case, you need to go to the 4S shop to check the sealability and desiccant of the headlights in time. Otherwise, the headlamp failure or insufficient irradiation will affect driving safety.
