Answer 1

the easiest way is to get some silica/dessicant out of a glazing shop most shops would have some its really cheap but messy to clean up after. just put it in the light and it takes out all the moisture and condensation. its what is used in double glazing its quick and yyou will defo pass it ive done it a few times before gud luck

Answer 2

Easy way is to remove the bulb and blow warm NOT hot air into the back of the reflector. It should dry out fairly quickly. You could use a hair drier and direct the air with a cardboard tube. If you can you should go round the joint between the reflector and the lens with sealant, and check for water leaks in the engine compartment. If it's a bit steamy under the bonnet the lights are the coldest place for condensation when you're driving along

Answer 3

Your light housing probalby has a bad seal somewhere that is allowing water in. I had this problem on an old Ford Escort.

The way I fixed it was I removed the whole light (or got under it, I can't remember) and drilled a few small holes in the lowest point. This allowed any built up water to escape, and allowed moisture inside to evaporate more quickly. The heat from the light, along with the holes, cleared it right up.

You may still need to clean the lens by removing the light bulb from the housing, and wiping the inside with a rag on a coat hanger or something.

Good luck!

If your car is still under warranty, take it to the dealership to have the entire light housing replaced under warranty.

If past warranty....the only cure is to do what mechanics do. Drill 2 small holes on the bottom of the headlights to allow any water to drain. Then a day or so later they cover those 2 holes and the seam with clear silicone.

A headlight is 2 parts....a back and front shell...where these come together is where water gets in. But they are glued together so you can't just pull them apart.

If you headlight is removable, it would be best to remove it to remove the moisture. There is no real fix on the market for this item. I restore yellowed headlights for people all the time but still only have this cheap fix for watered headlights.

the headlights are sealed units,moisture is getting in and causing in condensation.remove the headlight warm it to dry out the moisture then use clear silicone sealer around the edge of the lens(the prime suspect to be leaking)also check over the rest of the light for possible leak points.depending what car you have you may get one from a scrap yard for a few quid.

Answer 7

Ultimately you'll have to replace the lamp if it's so bad it affects the beam pattern. It means it isn't seal from the atmosphere enough. Sometimes just leaving main beam on for half an hour dries it out, but it will return.

Answer 8

If there is no crack on head lights, The problem could be due to the damage of headlamp vents (housing vents).
Head lamp vents can maintain the exchange of air in response to changes in pressure or temperature.If rubber seals are improper then it is better to fix it up first.if head lamp vents are clogged condensation on head lamp is possible condesation in head lamp can also be removed using air compressor
