Despite my best efforts to seal headlights, I am getting condensation in both. Occasionally, after heavy rain or car wash I can get a couple of inches of water. Other than putting in some goldfish, can't figure it out..

and if they're not rusted out from the inside yet, they will be soon... I hope someone comes up with a solution to this someday soon.

I'm ready to hook a vacuum pump to one and try to find where it's leaking in... it CAN'T all be condensation, at one time I had a headlight almost half full of water.

Please someone, tell us how to fix these headlights, please!

Take a drill , with a very small drill bit , and drill a hole or 2 in the bottom of the headlight , but be careful not to drill the wrong spot and crack it.This works very well , it lets the water out , and keeps the condensation down.The headlights on our trucks are known to do this , and its very common. <img src="/forums/images/graemlins/kewl.gif" alt="" />

I've thought about doing that, but was afraid that the bare edges of the hole would cause it to start rusting faster. I guess one could put a little rustoleum, or POR15 on a Q-TIP and protect the bare metal after drilling.

But, WHERE is the leak ? Why do some leak, and some don't ? Why is it 90% of the time only the driver side leaks ? Were all these lamps from one (or more) defective production run ?

If your worried about it rusting after you put a small hole or 2 in there , dump some of that stuff you put in campers to suck out the moisture.I have had the hole in my headlight for over a year now , and no problems , before it was always half full of water <img src="/forums/images/graemlins/scared.gif" alt="" /> And we get lots of rain here , but now its fine , 2 little holes.I did crack one when I drilled it , hit the glass <img src="/forums/images/graemlins/zombie.gif" alt="" /> but I had a spare.Its something about the seals on them , and where the rain from the gutter comes down on troopers that causes the problem.

When you take a cold beverage out of the fridge and let it sit a while you'll get condensation on the OUTSIDE of the bottle. Why? Warmer air reacts on the surface easily as it's not pressure/vacuum orientated. Quartz style lamps are similar to bottles, as they cool vacuum occurs drawing in cool (damp)air. As temperatures rise pressure occurs, since the air is less dense and lighter it will escape leaving the heavier moisture.
If there are no cracks or imperfections in the jug suspect the hallogen socket seal. And if you MUST drill holes, put a shielded one in the top to permit evaporation! Just my two cents...Cal

I didn't put a hole in the top as that would bring more water in , you want it to run out , and the holse I drilled alow enough evaporation , especialy when the lights are on and get a little heat in there.Not one problem since I did the holes , before that I was going to replace the light untill I found out what a new one was worth <img src="/forums/images/graemlins/scared.gif" alt="" />

Yeah, even used those housings equal a stocked aquarium!
A SHIELDED opening is what I meant (covered above, just a fraction of an inch will do). The sooner you can convert the moisture to a gas and spirit it away the better. Granted, turning on the lights or warm sunlight will cause the desired pressure, and an escape route at the bottom will flush out visible water, but warmer molecules of H2O will cling to the highest point (like clouds do)only to gradually drip across the lense (shortest distance to the bottom and closest to meteriological disturbance) at cooldown and end up on the base of the jug. If there is VISABLE water, there's a big leak.
Shoot, you could attach a tube to a drilled hole and mount it near the coolant fan's shroud exit. This would be the reverse effect of a pitot tube of an airplane's speedo, instead of pressure you'd get vacuum! Perhaps my background in physics is annoying, I'll try to refrain...Cal

Years ago when the ITOG board was active, there was a suggestion of brazing a tube with a bend in it to the headlight housing. Evidently some Dodge vehicles use a similar device.

After siphoning water out and replacing another bulb, I used some silicone to "seal the seals." Next day, more condensation... How does the water get in?
