headlight condensation

[zippo2341]

hey guys, recently installed a set of cobra headlights on my gt, upon doing so i decided to restore the factory corners as well as foglights. upon taking the slight haze out i now notice that condensation is forming on the insides. When i put the cobra headlights in i put a small bead of sillicone were the lense and housing seal together as backup, dont have any problems with them. Instead of dong this to my corners and fogs as well, what about drilling say a 1/8 inch hole somewhere on the housing thats not immediatley noticiable, do you think this will provide an adequate vent for the condensation to evaporate out of?

I was always under the assumption that they were sealed units? I know you can fail inspection for condensation in the lens.

I wouldnt drill anything in the plastic, I would consider looking into a new lens.

You can dry them out with a hair dryer and then pop the bulb in. this way you are not trapping moisture from a humid day inside them. But they should be sealed. My Lincoln LS had a service bulletin for condensation. I got new headlight assembly because of it.

take them out and let them sit in the sun for a day then seal them up. you should be good then

I suppose if you really wanted to drill a small hole, do it in the back where you won't see. Otherwise, just take out the headlights from the car and the holes in the back that the lights plug up to should help...just leave it in the sun. After that, just put a small bead of sealant around the lense/'body' of the headlight. When I sealed my tail lights, I used the RTV silicone sealant from Autozone and you only need one tube of it.

yea i was only gonna do it in the back somewhere that dust and crap hopefully wouldn't get inside. Its not first time ive lsealed headlights, just never noticed it before in the driverside corner lense. Ive had the same tube for the past 3 cars, each had all had this problem

Well if you go the drill route, you could always fill it back in with the sealant and just pull it out of it ever happens again. Although, I would try letting it sit in the sun for a while before drilling a small hole.

but heres the weird part, when i restored them the condensation wasn't there and i did take a quick glance to see. After i drove back to school it rained here for 2 days, then i went to show my room mate the new lights and the restored old lights and thats when we noticed it.

Dont drill a hole in my opinion, you wanna solve the problem not live with it...lol, just buy RTV clear silicon from pep boys or auto zone its like 10 bucks then reseal the entire housing. Trust me i had the same problem and this solved everything for me.

Best recommendation, set them on the driveway in the sun. Then re-seal with the silcone.
