What are the solutions for water inside fog lights?
2 Answers
The solutions for water inside fog lights are: 1. If the fog light itself has cracks, it needs to be repaired at a repair shop; 2. If the fog light is damaged due to external force, causing moisture to enter the inside of the fog light, the fog light should be removed and replaced with a new one; 3. If the sealing ring at the back of the fog light is loose or damaged, causing moisture in the air to enter the inside of the fog light, the sealing ring should be removed and reinstalled or directly replaced with a new one; 4. Simply turn on the fog light and use the heat generated by the light to evaporate the moisture inside the fog light. After the moisture has evaporated, use tape or other sealant to completely seal the fog light; 5. If other equipment causes moisture to appear inside the fog light, check whether the water tank is leaking or the windshield washer reservoir is damaged.
Oh man, last time my car's fog lights got waterlogged and it was a nightmare! I was driving through heavy rain overnight, and the next day I could see water sloshing around inside the fog lights. I quickly removed the rear cover to drain the water and found the sealing rings had aged and cracked in several places. The mechanic at the auto shop replaced them with butyl rubber seals and used a heat gun to dry out the moisture inside. Now, every time I wash the car, I pay extra attention to the drainage holes around the fog lights and use a toothpick to clear them regularly. The mechanic said if the lamp housing is warped, the whole unit needs to be replaced—otherwise, even changing the seals ten times won’t stop the leaks.
