The head lights on my car fogs up when it rains. Is there a way to fix that problem ?

Answer 1

There is but I don't think you want to try it. Just replace the 'problem child'.
It would involve separation of the lens from housing. Baking for twenty minutes @ 200 degrees. Then resealing the two halves.
A cheap way is to drill two holes in the lower section of assembly so air can circulate through the unit. Heat from the bulb will dissipate moisture.

Answer 2

OK if it is a contour headlight meaning the headlight shapes with the car.There are vent tubes on either side of the headlight assembly, they will clog and not let the moisture evaporate. These are NOT a sealed light, the bulb is!
If the bulb gets replaced completely then there is a very small vent in the top only of thes sealed beam and that does get clogged.
No real need to replace the bulb.

Answer 3

You don't mention what type car, but about the only solution is to replace the headlight. You could try to seal the leak, but you'd never get all of the water out, and you're still going to fog up.

visit your yellow pages and call around to local salvage yards to see if your headlight is available and at what cost. You might even find it on ebay.

But to be honest, as long as it's not blowing bulbs or causing you not to be able to see at night, I'd leave it alone. Keep in mind, whether you spend the money or not, eventually this car and every car you own is going to end up in someone's junk or salvage yard.

Answer 4

This problem is caused by either a leaking seal around where the bulb goes in the back or the actual seal around the lens leaking (more likely). If it is the lens leaking, the only reliable way to fix it is to replace it. I have seen people try to seal it with silicon, but it never works and it looks terrible.

Answer 5

You are seeing condensation due to the temperature difference between your headlights and the air outside. There is moisture in the glass cavity so it sounds as if your lights are not sealed. Alternately, they may be sealed but moisture infiltrated at some point in the past. You could replace the headlights.

Answer 6

You have leak in the rubber gasket around the plug in your headlight goes into you need to open it up on a dry day clean and replace it.

Answer 7

my car use to do that,and i got some clear silicone sealer and went around the lenses,and it never did that since.whats wrong is the seal is bad around the lenses.
