does any one else keep gettin cond. in there headlights? how can i stop this???

 

since you installed them BEFORE you should have put clear silicon around them (most of them have sucky sealing properties...that's how you get them soo cheap) then you should do what I've done in the past. Get a really small drill bit and in the bottom of the lense at both corners (inside the lense area) drill a hole, then pop the hood and in the back top area of the light (still inside lighted part of the housing) drill another hole.

what this does is the bottom holes allow air in and liquid water to drain out. The hole in the top allows the vapor to travel out....then no more condensation. simple as that. I've sold two cars with this done to the headlights and nobody EVER knew because the holes are soo small and right at the edge that you can't see them unless you either look hard or KNOW they're there.

This is a good idea!

But the problem with this is over time, your lenses will get dirty for allowing amounts of air in. I would suggest putting extra silicons only.

actually, you won't have that problem either. I had this done for about 4 years on one car and 3 years on the other and neither one had yellowing...I did clear corners later on with each car. yellowing is caused by excessive HEAT inside the lense housing which "cooks" the plastic over time...not by sunlight...which is why some cars have it and others of equal age DON'T...due to the amount of time they each had proportionally running at night...

the holes in the housings ACTUALLY act as vents also thus helping cool down the housings...especially at road speed of 55mph and above...just imagine a small forced air vent of that size at 55+mph...not a lot of heat in there...this ALSO helps to extend the life of the halogen bulb as it helps to keep it cooler than normally...and if you've ever grabbed a hot halogen bulb then you understand why it could only help to cool it.

one last thing. no, you won't have to worry about water on the bulb either being that you should drill the holes at the BOTTOM of the housing and not in the dead center. EVEN under horizontal rain you won't have the "splash" effect from such a small hole.

I can try to take some pictures of my grand cherokee which I've done this to as it had the FACTORY headlight housings holding water in them. I did this to it and they were completely clear in about an hour and no problems since then! oh yeah, past cars I've done this to were a 98 civic ex, 94 mustang GT, and 93 BMW 325i

 

ok, so once i put silicone around the housing, hows does the water vapor thats already in there get out? wont dirt stick to the silicone? the only time i see the cond. is in the sun up and sun down...

 

let the silicone dry before you put them back on the car chief....

and the water gets out through the drain holes that are already on the housings...look for black "L" tubes

 

yea i see the black L tube things, how big of a hole should i drill, and any spec. spot for it?

 

i say no drilling...the drain holes should be fine.

just reseal and let dry, then reinstall

 

...i, dont think it has drain holes, each light has 2 vent at the top though.

 

the black L's are the drain tube...seal the top vents as well...thats just stupid
