moisture in the tail lights?

While i was working on the diff fluid change in my TJ, I noticed moisture buildup at the reverse lens of the tail lights.

What's the likely place the water is getting in? I'm assuming around the lens and it just needs to be sealed up. Figured I would ask on here before tearing it apart.

I did a search on the forum, but nothing came up except for folks blowing fuses because of water in the lights. Trying to avoid that next phase of water getting in there.

Yepper, same thing on mine. They work so I am not worrying. OTOH if someone has a fix, I'm paying attention!

Yeah, prolly a gasket issue...mine both have moisture in them and have had it since I bought my Jeep 2 1/2 years ago. Hasn't damaged anything thus far so I just ignore it. You could probably silicone the assembly to the body, dry it out thoroughly and then silicone the cover shut to seal it. You'll have to redo it when you replace the bulbs...but that would solve it. Or just live with it...

I noticed moisture on one of my tail lights as well. I took off the tail light lense, put a very small beed of some flowable silicone glass sealer I had from another project. I think it was made by Permatex. I put it around the inside edge of the lense and let it dry (not sure how long it takes to dry because I let it dry overnight). It'll form a nice clear silicone type of gasket. In the mourning put the lense back on and haven't had any moisture since (about 8 months)

I drilled two small holes in the bottom lens the curved one to let the water drip out if too much accumulates and that saves the bulb

x2 on the tiny holes. I did it with the end of a paper-clip, heated with a lighter. Might even be better that way, because you won't get any fracturing of the plastic.

Works a treat on the rear window hinges on the hardtop, too. No more water dripping on your head when you open the window, the day after it rained.

Ah-ha! That's what it is

Thanks folks- appreciate the help. Just wasn't sure if it was between the lens cover and light assembly, or next to the body.

Guess I got some caulking to do!

Cheers!!

Not so bad. I was waiting on somebody to ping me for caulking instead of silicone.

Maybe I should just go the nitrogen route. I hear the molecules are larger and therefore dont leak out as easily.
