1. Car washing or wading in water causes fog

In addition to temperature differences, fog entering the headlight assembly is mostly caused by wading in water or improper car washing. When cleaning the engine, you should use a wet towel to scrub it, or use compressed air to clean the inside of the engine compartment. Rinse directly with a high-pressure water gun. If a car owner often uses a high-pressure water gun to flush the car lights or engine, it is easy for water droplets to enter the vent holes, and fog will form in the car lights.

In addition, vehicles that frequently wade through water can easily cause fog on the car lights. Some self-driving enthusiasts like to drive through deep water. Usually, when the water depth exceeds the wheels, water will enter the car lights from the breather pipe, and water will enter the car lights. Not only does it affect lighting, it may also damage the headlights.

If it is caused by temperature difference or moisture, for example, if the car lights are used for too long at night and there is fog in the car lights the next day, just turn on the fog at this time. Turn the low beam or high beam on for about 10 minutes, and the fog in the car lights will slowly disappear.
