What are the solutions for foggy car headlights?

Solutions for foggy car headlights: 1. If there are not too many water droplets or a small amount of fog, you can turn on the headlights for a while, and the fog and water droplets will evaporate as the temperature rises; 2. Parking in the sun for a few hours can also help evaporate the moisture; 3. Open the dust cover at the back of the headlight, take out the headlight, and use a hair dryer to blow it; 4. Check if there are any damages on the headlight cover, inspect whether the seal at the headlight cover interface is tight, and see if the rubber strip is loose or damaged. If the seal is intact, there might be a leak in the headlight cover. In this case, seek professional repair services to fix it with transparent glue.
I've worked in the auto shop for over a decade and often encounter foggy headlights. The main causes are aging seals or improperly closed lamp covers allowing moisture to seep in. Patience is key when addressing this issue - slight fogging can be resolved by driving with headlights on for half an hour in warm weather to dry it out. For severe cases, use a hairdryer on low setting from a distance to blow warm air at the housing for a few minutes, but avoid getting too close to prevent melting the plastic. Always inspect the lamp cover edges and seals - replace them if you find cracks or wear. Clear any clogged ventilation holes too. Prevention is crucial - ensure lamp covers are tightly closed after car washes or rainy days, and park in dry locations. Don't underestimate fogging - it reduces brightness, compromises night vision, and increases accident risks. I recommend checking the seals every six months and seeking professional help immediately if anything seems abnormal.
