Misting Headlights!!! Grrrr

[Gooner_Mike]

You have two choices really: either seal the units so that no water can get in... or allow the free movement of air in and out. The best way I found was leaving the covers off the lights and going for a drive. The engine heat and circulating air dried them out a treat. I have heard of people using vaseline on the seals to keep the water out! Now I have HIDs, the extra heat seems to dry them a bit too! Best way is to drill some holes in the back cover probably... Good luck!

I have exactly the same problems with mine.... Given up with it now as im on my 4th driver side, 3rd passenger side and had the full set of rear lights replaced under warranty too and they all do it!

They told me its not a warranty issue if its only mist in the light, it needs to be water droplets like in the pics in the previous thread.

I took the bulbs out and used a hair-dryer to dry ours out, but the heat caused the bulb shields to bend up a bit - doh!

Gingerly bent them back down again so they're centred on the front of the bulbs and they seem OK, but was panicking for a while thinking I'd have to replace the lamp units!

I have managed to come up with what I think will be permenent solution! Now before you all start calling me sad!lol I'm an IT Technician ;-) haha

What i'm going to do is drill a circular pattern of holes the size of a pint glass in the back of each headlight cover, and then mount a computer CPU fan on the back of it to draw air out of the light unit and into the engine bay (thus keeping a constant flow), then will wire in a resistor on each side then then connect to a switched live so they only run when the ignition is on! WOOP WOOP. Hopefully will work, yes I know I could just put silica bags in, but i'm a geek like this!lol

Sounds like an interesting project, keep us informed

haha i like ur idea, let us know how it goes, pics would be awesome too

I had an idea similar to this for a permanent solution...

There is a hole in the bulkhead on either side that you can feed amp cables, boost pipes etc through, so i thought about putting an 8mm pipe fixed into the heater ducts on each side down the wings and feeding each light with warm air. I only get this problem in the winter, and i reckon this would cure it.

Plan:
Shut both side vents in cab, turn heating on, warm air goes down ducting into headlight and eliminates the moisture. Might even work with vents open, i dont know what pressure would be required.

Im a Mechanical Engineer btw, notice the lack of electronics!

silca gel packs work a treat

Thats boring tho!lol Your not plumbing or wiring Scott!hahaha
