    Iam getting moisture in my driver side headlight? I got after market headlights from Ebay & the HID Xenon lights. I've had this problem for awhile now (since last winter).I think the moisture is coming through main headlight rubber peice. Its strange my passenger is perfect, I've tryed electrical tape, clear sealent, duck tape. They say duck tape can fix anything but not this. ANY suggestions?

    Did try baking them in the oven? I had some aftermarkets on my Mustang and I baked them then sealed them with RTV sealant.

    No I haven't, so you think its a bad seal? Where can you pick up this RTV sealant at?

    most likely a bad seal yes, try window weld its what most of us have used with good success for the bhlm, available at most auto part stores, may have to be special ordered but usually only takes a day or so....

    None yet! It's new!
    Getting the moisture out is the least of your problems. It will just come back unless you fix the reason behind it. There must be a leak somewhere that needs to be sealed.

    I have stock headlights. One of them would get condensation inside... I'm not talking vapor... I'm talking enough water that it would run down the lens in droplets. The dealer didn't even try to fix it - they just put a new one in under warranty. If you bought something aftermarket, you're paying your money and taking your chances.

    I know nobody really wants to hear this, but the stock headlights are not bad units. They focus the light well and when you use a good quality H4 bulb, they work quite well. If you need more light, put on aux driving (distance) lights, or fogs if you're in an area that really requires them. True fog lights are virtually useless - they cause glare and they're only usefull at extremely slow speeds.

    My opinion of course, and most here will not agree, but that's what makes our country great. I can have a different opinion than the next guy. :)

    You could also use silica gel packs to soak up the moisture. Then just run a bead of silicon around the edge of the headlight to re-seal them.

    I actually agree with you about our head lights. I'm not a fan of HID's myself. They are blinding to other people no matter how you aim them. But I disagree with you about true fog lights. 1st you should not be going at a high rate of speed in the fog, you can't see. True fog lights light up directly infront of you rather than try to break through the fog. Lets you see the lines and anything that is directly infront of you. And since you should be driving slow, that is enough light for the fog. IMO of course. Sorry not trying to thread jack.

    No prob, Deevon - I'm not disagreeing with you either. :) The problem is with people running their fog lights at other times. When used in the fog at slow speeds, they're fine. When people run them in the rain when the streets are slick and reflective, they cause problems for others.

    Regarding the moisture problem: I think KPT is on the right track for the solving the problem with the least hassle. Do what you can to get the moisture out and run that clear RTV around them at the joint. That would be doing the easiest thing first - not disassembling them using an oven or other nonsense.

    "Removing" the moisture by heating somehow, like with a hair dryer, etc. will work temporarily, but usually the moisture will re-condense and the problem is still there. Maybe if you left them in an oven on low heat for a long time, they'd dry out, I don't know. The silica gel might work, I don't know that either. Sealing the leak is the key though, after you dry them out.
