My week for advice. I have a 2013 Itasca Ellipse which is new to me. I have been fixing a few minor things. It rain very hard a frequently a few days ago. I ended up with moisture in the tail light. The sun beats on it most of daylight hours and the moisture doesn’t seem to be dissipating very quickly. Is there a moiture release that might be plugged or can i drill a small hole that i could cover with small piece of tabe when dry? Or do i need to remove and dry. I can’t find how the moisture entered.

I suppose remove lens, dry out, replace with sealant would be right way, but a small hole drilled in the bottom of lens probably would work also. no need to tape it over.

Mine have factory vents at the bottom...the rubber seal seals all around the light except for the small opening at the bottom. Any water that gets in should eventually dissipate or drain out.

Sun beats on light and the warm air expands. In the evening the air cools and draws moisture into the light. The next day the air expands again BUT some of the moisture stays. Repeat above.
Drill the hole or remove a portion of the seal at the bottom.

I would look closely at the fixture. There should be a low point drain.
Look at lense and get manufacturer number. It is even possible that the fixtures are installed upside down.
I would get some electrical grease and coat the lamp bases and the socket to prevent corrosion.
Might think about LED lamps if they are not already.

If the lens is removable and can be installed in two different orientations, maybe it's installed upside-down, with a weep hole at the top rather than the bottom. If there's caulking around the fixture, check that it isn't blocking any weep holes, too.

I did have to drill drain holes in the taillights of a car I owned some time ago to keep them from filling up with water. If you do put a hole in, leave it uncovered.

I think it is right side up given orientation of fasteners. I am going to give it a bit more time to dry and if it persists make a weep hole. Thanks.

Pull it off, put it in a 500 degree oven and order a new one.

If not actually leaking, condensation can be a tricky culprit.
I have moisture in one clearance light - and my rv is under a roof!

don't drill a hole in the base because the water will just get between the walls and cause dry rot. try to drill a hole in the lens itself.
