Hey so i got my head light out and i have it inside drying out the moisutre.. is there anyway i can find out where the moisture is getting in? tehres no visible holes or cracks i was just gonna silicone all the way around where the lens meets the assembly anyway but i thought id ask

 

Hard to say. You could fill it with water and see where it leaks out. Could be a bad rubber gasket/seal where the bulb goes in (I think the seal is on the bulb, but I'm not sure).

You can help dry it out with a hair dryer. You want to blow very dry air in there to get rid of the moisture. I had one headlight on my Contour (yes, I had one of those) that would get moisture on the inside on occasion. I just pulled out the bulb and blasted it with a hair dryer every couple of months.

 

mine does it every once in awhile but its a bulb...run a bead of grease around it or RTV silicone

 

My tail lights did that, Ironically I had to drill holes in the back of the lights to let the air circulate. Something about it being completely sealed acts like a green house where condensation gets inside.

 

My drivers headlight get moisture in it. Never could figure out from where. Quit worrying about it and decided that as $$$ permits I will replace them, they are getting foggy too.

 

If you drill hole in the back of the headlight so air can get in, when it cools down it will not condensate as the outside air temps will be the same as the inside air temps. Other than that, as said above, you can silicon them better to keep moisture out as they cool down internally.
