Condensate in lights.

chrislcrews · May 20, 2016

I have a 2015 gmc I have aftermarket anzo lights.

I have three small a holes drilled into the light underneath it because it had condensate issues when first put it. It is my 2cnd pair. I do not have condensate issues when I wash the truck only when I drive in the rain. I recently had HIDs put in the kit from retrofit... The right does not condensate only the left. Could the installation be the issue? Even if the other light does not have this problem?

Also any tips on what else I can do to fix this? Should I drill more holes or what?

I've been toying with buying new lights. Prolly recon but I don't want to do that if I can avoid it. I like the anzos I just don't want the condensate issue anymore...

If I followed this correctly the holes you drilled did not help at all and I'm not surprised. Use some sealant to fill in the holes and then seal the edges of the assembly where the lens and the backing meet. Any holes or cracks will allow condensation.

Put some of those absorbing gel packs in their. That cleared up mine

The shop I had install the lights previously before drilling these holes said the places an air hose I tot he light and turned it on, this way they can see where the seal is not sealed at. Said that everything looked great and found nothing... Suggested I put holes in the lights so I did.

Am

I suppose to seal in the dust cap with the HIDs installed?

And the asorbing gel packs I'm afraid would get too hot.

Other suggestions? Please?

Ive had mine in for months. No problems, you can even put them in the oven to dry them out. So they're fine in the headlights

Did you just pop them inside behind the dust cap?

Asells · May 20, 2016

Ya, I just tied some string to them just in case they didn't go farther back.

Where do you buy these packs at?

Asells · May 21, 2016

Ebay. They are the stack on brand. http://m.ebay.com/itm/Stack-On-Safe-N-Dry-Desiccant-for-Long-Gun-Safe-Cabinets-10-Pack-New-/262336616313?hash=item3d147b1779:g:HJAAAOSwr7ZW6CDH

I believe walmart has them as well.

If you have holes drilled the desiccant bags won't cure the condensation issue. Also, any other leaks where wires pass thru are an avenue for moisture to enter.

My recommendation is to check all possible moisture entry paths and ensure they are sealed. The holes you drilled should get a small patch of GoreTex glued around the edges. Once you've done this, the desiccant should clear up the trapped moisture.

Alright I'll get the holes sealed up. I was told that is the solution. Like I said the left one only fogs up when I drive in the rain not when I wash it.

How often do I need to replace these gel bags?

Shouldn't really need to replace them. There is an indicater on them that turns blue when they have moisture in them. Then you just pop them in the oven to dry out and reuse them. I haven't had to take mine out yet.
