What to Do When Car Headlights Fog Up?
1 Answers
Solutions for foggy car headlights include: 1. Use an air gun to blow air into the headlight to speed up defogging and dehumidification; 2. Remove the headlight dust cover to allow quick release of water vapor inside the lamp; 3. Turn on the headlights for about 30 minutes to increase the internal temperature and accelerate the evaporation of small water droplets inside. Causes of car headlight fogging are: 1. Cracks in the welding between the headlight and lamp housing; 2. Driving through water or in rainy conditions; 3. Aging of the lamp cover rubber; 4. Cracks in the headlight sealing cover; 5. Detachment of the vent cap, vent tube, or breathable membrane; 6. Using a high-pressure water gun to wash the car.
