Moisture In LED Tail Light

[Florida Bob]

I have a 2019 Keystone Cougar 22RBS travel trailer. I can see moisture (condensation) inside one of the tail light enclosures. I tried to pop open the enclosure but it won't budge.

My questions are: Has anyone else seen this issue, and what was the fix?

Outside ring pops off. The moisture looks like it’s in the “center” piece. I have only replaced them when that happens (under warranty).

I would drill a small hole in the bottom to let the water drain. Also make sure the top edge is sealed with silicone caulk.

Thanks for your replies. I could go either way, but I should probably take advantage of the new RV warranty and take it in to the dealership.

Once I moved it under my RV carport, The tail light dried out on it's own. So, I ran a bead of clear ProFlexRV along the top of the clear section. After camping in the rain, there is NO moisture inside the tail light!

I had the same problem with that light, tried drilling small hole in bottom but water never drained.

Ultimately had it swapped out under warranty.

There were several runs of 2019 Cougars and Montana’s that had water buildup in tail lights. Replace them under warranty.

Sometimes you will find there is already a weep hole that is supposed to be at the bottom, but the manufacturer installed the light upside down.
