What Causes Water Mist Inside Headlights?
1 Answers
Water mist inside headlights is caused by temperature differences and improper car washing. Temperature differences: After prolonged use of the headlights, their temperature rises due to operation. If the lights are turned off immediately at this point, the significant difference between the external air temperature and the internal temperature of the headlights can easily cause mist to form inside the lights. Improper car washing: Improper car washing refers to using a high-pressure water gun to rinse the car headlights. Since the headlights are not completely sealed, water droplets can easily flow into the ventilation holes during washing. This can lead to water droplets entering the headlights, which, due to temperature and other factors, results in mist formation inside the lights.
