Okay, I've gone through the garage and searched for anything pertaining to headlights and no one seems to have a post about restoring the INSIDE of your headlights, and the airtight integrity, respectively.

I cleared out my headlights and installed halos a while back, and I think the epoxy I used to seal them back up is actually melting in the heat here in 29 Palms. I have a nasty amount of moisture in both my headlights.

SO. I'll be doing a complete overhaul on my headlights soon, including Vleds for both turn signals and DRLs. Along with this, I'm going to really get serious with how to best seal these puppies up. I know ackTL05 is probably the best person to talk to about this but I don't want to PM him with inquiries that he probably gets way too often. So if anyone is feeling up to it, I need guidance on doing a pro-style headlight restoration

Also, since there is quite a bit of moisture on the inside of the headlights, there are probably water deposits in there too which I will have to clean up. I need to know how to clean up the insides without scratching or marring the plastic.

TYVM in advance!

 

If there are indeed "water-deposits" or little puddles in your headlight, MAKE SURE you don't tip the headlight too much or else the puddles can make its way toward the ballast which WILL fry it.

Once you open up the headlight, a clean microfiber cloth should be good followed by a terry towel.
To stay safe, I wouldn't use any household products to clean the lens. Just water does the trick.

If your headlights were like mine and you had condensation for a while, you'll have to actually scrub the mineral deposits off the inside of the lens. Just wiping the lens left the deposits so you can still see the outline of the condensation where it used to be similar to water marks you get on your windows if you don't dry them after washing the car.

 

Awesome advice, that's exactly what I was looking for. Thanks!

 

Headlight work is my specialty I run a business doing headlight and lighting work.

A common misconception is that a headlight seal needs to be airtight. People don't understand how moisture forms. Think of it this way, does a sealed water bottle form condensation when you take it out of the fridge? YES it does. So myth debunked. Also, in almost all headlights there are vent holes on the back of bottom to allow some pressure to release, but its usually into a form of a hidden tube so water doesn't work itself in. The only way a headlight can condensed from a bad seal, is if the seal is so bad that water actually leaks through it.

That being said, there is also a difference between water leaking and condensation, you need to determine which one yours is. Also, condensation can form from other causes too like moisture trapped in the headlight when you sealed it, or perhaps a bad bulb gasket, and/or ballast gasket.

 

Very good to know, thank you. With that being said, I think it is probably just my epoxy that is failing because it tends to fog up after I wash my car.

 

I'm going to make a badass writeup for this. Just got back from the store, got some Devcon Waterproof Epoxy, assorted exactos, files, etc. Should make it happen this weekend ^_^

 

honestly though epoxy isnt really good to use as a sealant. If you re-do the sealing process I think you can make it seal right. I prefer that method because it always looks a lot cleaner in the end. having excess glue/silicone/butly around the edges may not bother most people but when I see it, I think it makes it look kinda ugly
