water in taillights

[Mstoad]

Hi all I have a 2016 3010 Sunseeker class c motorhome. Have a problem with water getting into rear tail lights. How should I rectify this for future. Cannot keep paying service guys to fix things. Senior lady needs help!! I'm in southern Ontario Canada.

Msttoad, is the water sitting inside the red lens or is the water getting BEHIND the lights and into the camper wall? A picture if possible would help. Jay

If inside the lens drill two drain holes on the bottom. Use clear silicone lightly on 3 sides of the lens. leave the bottom open.

If behind the lights ( I would look anyway) seal the holes were the wires go in

I have the same problem on my 2016 3010DS. The suggested solutions confuse me because these are LED taillights. The condensation is on the inside of the lens wich is also the component board surface for the LED's. In Vermont this will not pass inspection. They replaced it and a month later the new one looks just like the old with condensation in there. Can you provide more clarification on the suggested fix please.

Hi we did drill a small hole and hopefully have resolved the problem

We have a full width slot at the bottom of the lights that stops condenstation .

A close up photo would be very helpful.

Our original lights had two screws attaching the backup light lens to the red portion of the light. Because they were leaking, we had the lights replaced with an updated version when we were at the 2016 FROG Rally. The updated ones have four screws attaching the backup light lens.

The leaking stopped for a while with the new lights, but we did have one additional problem. While attempting to tighten things down due to a new leak, I discovered that one of the upper mounting screws for the left light had a stripped out mounting hole. I glued some pieces of toothpick into the hole and remounted the light. Now they stay dry inside and have been so for nearly two years.

The lights have to be very tightly mounted to avoid leaks. Just be careful not to tighten to the point of cracking them.

IF tightening them keeps out the moisture then the answer is easy.
Remove the lens.
Dry thoroughly!!!!
Apply a tiny bead of your favorite flexible
white caulk to the edge of the lens.
Go around each screw and put a tiny dab under the screw heads.
Re-attach lens.
I had to do the above to my previous Rockwood on all the clearance lights.
They all leaked.
Some leaked inside!!
The tiny bead of caulk stopped all the leaks and you can't see it because even tho the lens is amber or red the side of the rig is white so the caulk doesn't show.

Go camping!

Can anyone help me find a replacement taillight? Mine was full of water too, but having a hard time finding a replacement to match the other side. Here's the photo...(It's a vertical orientation, not horizontal). 2016 Sunseeker 2650. It has LED's on top and bottom and a bulb in the middle....thanks!

Best bet is to contact Command Electronics: https://www.commandelectronics.com/contact

The newer lights are all led and they are sealed. You may end up replacing both.
Here is an example: https://www.etrailer.com/Trailer-Lig...cs/CE44VR.html

You will need to verify size.

While I was here I had the tow truck flip you back on the wheels.

Huh, my 2016 3010 DS had tail lights filling with water on the maiden voyage from New York to Missouri. On the trip home when I noticed it I loosened the screws that hold the tail lights in and the water drained out. Left the screws slightly loose for the rest of the trip. I have the same lights as SS Cruiser. The problem was a terrible job from the factory sealing the light to the body. Cleaned up the messy work, tightened the screws properly, sealed the joints and no more issues.

This is probably why you have water in your taillights - same as I had:




(Ignore the yellow wire nuts - they were temporary until I finished the project, then I used the proper crimp connectors)


It appears they forgot to install the gasket before hooking up the wires, so they tore the gasket, tossed it in the hole, and installed the lamp assemblies.

Mine were full of water not long after we brought it home...

I removed the assemblies, cleaned it all up, then sealed the entire perimeter with clear sealant w/o the gaskets. They've been clean and dry since then.

Drilling holes in the bottom is doing nothing more than hacking at the symptom. As the hole housing the assemblies also opens to the inside, it's an invitation for disaster down the road because you are still permitting/inviting the moisture to invade the space:




To do it right, remove the assemblies, clean, clean, clean, then use a good quantity of clear sealant around the perimeter and in all screw holes, plus around the perimeter of the clear backup lens.

Results 6+ years later:




Detail - yes, there's a fair amount of sealant - but NO moisture inside my lenses!



While I used a water based sealant, this is what I'd suggest:
