    Re: How to fix or clear my headlights

    You are going to have to...

    1. Remove your front bumper
    2. Remove your headlights from your car
    3. Heat up the glue on each housing so you can remove the lens from the plastic gray housing
    4. Re-attach the plastic lens with a good glue/sealer after completely cleaning and drying the inside of the headlight housing and let it sit and dry all the way through
    5. Also, it is not a bad idea (since you may not know exactly what is letting moister in the headlights) to remove the two black access covers on the rear of the headlight housing so you can clean the seal and inspect the gasket... then make sure the gasket is seated correctly and the access covers are reattached securely

    Also, I can't really tell in the picture... But did you add aftermarket HIDs? If you did and you drilled into the housing to allow the wires access and did not properly seal/watertight the remaining space this will absolutely be a major contributor to your problem. That does appear to be a severe moisture issue and since it is identical on both headlights it makes me think this may be the real problem.

    As long as they haven't been that way too long, and the corrosion hasn't started, you can remove them, dry them out, and reseal the clear lens to the body.

    I don't think it's actually necessary to remove the lenses, and take the chance of damaging them with too much heat, but rather by simply applying a new bead of sealant around the outer seam, it can be fixed.

    There a SO MANY posts on this with peoples experiences doing it,,,, you just have to Search on "condensation" or "moisture" in this forum to research it and see what others have done about it......

    I am going to take it to my cousin's friend who installed HIDs on the car to see if it can be fixed.
    I really don't want to shed out $800-$1000 + for new headlights but I hope it can be fixed.

    Yes, I thought that was most likely the issue given the amount of condensation... Tell him to remove the headlights and completely dry out the housing (blasting a heat gun into one of the access covers on the rear of the headlight until dry should do it) then just put a liberal amount of some kind of a sealer to make sure no air can get in or out of any part of the hole he made in the housing to install the HID wiring, then you should be all set.

    After installing my HID's I had a similar issue, sealed everything twice and there was still a leak. Turned out to be a collapsed gasket.

    Re: How to fix or clear my headlights

    I was told twice now to make a really tiny drill in each headlight unit
    But I dont know where to find something so small that'll drill thru so the air can come out

    Really bad advice (you're talking to the wrong people....)

    Dry it out, seal ti up, and you'll have no more problems. Holes will only create new ones

    The hole drilling generally works on 92-97 Seville tail lights because the moisture drains out the bottom. Those tail lights were also small, so there was less moisture per light to drain. That's likely where the idea came from, and I cant imaging it being effective on a large headlight like this.

    In addition, holes introduce the possibility of cracking.

    The guy that installed HIDs on my car also tried to get the condensation removed by blowing air pressure (it did work) for the first few days. Then passenger side headlight seem to gotten condensated again.

    I have resealed both of my headlights. This is a very common issue.

    Take the headlights out, take the covers off, put a bead of clear silicone on there, and put the covers back on. You'll be good to go.

    This was done and only 1 side is good, the other side went back to a little condensated but not as much as before.

    Your problem may be on the back of the housing then. It is likely where the wires come in. Make sure that is also completely sealed up.
