2008 Fleetwood Sun Valley tail light issue

[Doom]

I bought this pop-up 13 months ago. I have used it 6 times as we bought it right before the snow started to fall last year. When we took it out of storage this spring to clean it up and go camping we noticed the right tail light is not working. My husband had bought a new truck and we thought it might be the connector on the truck....nope. The bulb is good yet the thing wont work! Any ideas as to what this might be and how to fix it?

Had the same thing happen on our 99' Coleman shortly after we bought it. It was corrosion in one of the socket bottoms. The way the snap-on taillight lens fits on the taillight base would allow water to trickle in between the red lens and the base unit of the taillight. After I cleaned up the corrosion and snapped the lens back on I put a bead of clear caulk where the lens meets the base unit. If I remember right, one of the taillights had 2" of water behind it. And wouldn't you know this happened just before we were to leave on a trip. One note: I spray a little WD-40 into the trailer - tow vehicle connector every few months to keep it from corrosion forming.....
