I'm trying to get the moisture out of the composite headlights on a '95 Taurus. I removed the entire assembly from the car, removed the bulb and rinsed the assembly clean and then put it in the oven on the warm setting with the door cracked open for several hours to evaporate out the water. Once that was done, I reinstalled the bulb using some dielectric grease on the o-ring seal and reinstalled the entire assembly. No moisture. A month later, there's moisture on the inside of the lense again. No holes or obvious cracks. Anyone have a solution to sealing out the water on these units?

When the air inside warms up, some of it will escape then when it cools down moist air will get sucked in and then you have condensation. It's like the moisture I used to get under my watch crystal. It's hard to keep this out unless the unit is hermetically sealed.

My mom used to have a 93 Taurus...did the same thing. Never could get rid of it even after some of the steps you mentioned above.

Same problem with my '02 oem headlight, driver's side. Finally cured the problem by going with the "sports headlight" conversion. Should have done it sooner. Now I can see where I'm driving.

About the Taurus, try some sealant around the outside of the headlight, where the clear lens meets the plastic.

It's probably just the blinker fluid leaking into the headlight. It won't hurt anything

You know, I think he might be right. I get mine from here

I had the same problem with my old Thunderbird. I took the lights off, left them in the sun to evaporate all of the moisture then ran a bead of gasket sealer all the way around the crack between the clear lense and the plastic back.

They never fogged again!

Man I'm sure glad you posted that link. I didn't know where I was going to get mine.

OK, I'll dry them out again and seal them with silicone to stop the blinker fluid leak.

The only cure on my 99 was to drill a very small hole and leave it open in the lower corners of each headlight. I worked well for the last 4 years I owned it.
Now on the 05 the foglights fogged up and they got the same thing done to them. It may sound crazy but it works and others have done it.

I've had a similar problem for years & its frustrating!

My problem is on my boat though - The front light gets condensation in it (its well sealed). I don't go out on the lake at night/early morning, but occasionally do...

And of course every time I do I end up buring out a light bulb within 5 mins when a drop of condensation falls on the hot bulb....

**** things aren't cheap to replace either! Now I have to keep a couple spares in the boat, and IF I think about it, take the cover off the day before & wipe out all the condesation.

I wish there was a simple fix for this!
