45 some help there, I would use urethane not silicon. Silicon should never be used on an automobile. I know you were using it on plastic but just a heads up silicon promotes rust and really does not sick or seal well in the conditons it will be put though on a car. Urethane is what the auto industry uses and it will seal and stick to your headlights much better.


Thanks, I think I will try using teflon but now that I have holes in my light, I'm not sur if it's gonna work. For the silicon, I tryed once to put water in the headlight to see from where or even if water could get out or in. My tail light was full of water when y bought my car and I removed it, sea where the water could get in and sealed that part whit silicon and it worked ! But the headlight don't seems to hallow any water escape, so it could be by the bulb but like I said, with the holes, not sur its gonna work. By the way, sorry for my english I usually use lot more french :p


there should be a drain on the lights, a little piece of black hose coming out usually in an elbow shape.maybe they are stopped up just a thought i would seal the holes if you can. you may need new headlights at this point.


I know what you're talking about theses hoses aren't blocked but I think I will remove them so more air could came out. Maybe with urethane I could seal the holes ? With silicon it work I've and it try worked well, after two days there was lot of water stuck in my headlight. Another thing that may work but I'm not sur... Even if their is moisture in my headlight, it's seems that it's only when my light are on that condensation appear because of the heat. If I put some xenon light instead, maybe they heat less and their would be less condensation? Or maybe it would be worste because the heat made them dry?


not sure if the bulbs well help but surely could not hurt the situation.
