Winnebago Vista taillight gasket

[garyemunson]

Many Winnebago Class As(and other RVS) have this taillight assembly. The problem with it is a simplistic design that requires the gasket always be in good shape to keep water out of the back of your RV. You cannot just seal it to the coach as the assembly needs to be removed to replace bulbs. I was looking at the gasket on my 2015 and it was already deteriorating. Command Electronics sells the replacement for $1.50 and it's a REALLY important thing to keep on top of, just like seams on your roof. Add this to your list of things to do if you have these lights..

Wanted to add an update to my experience with the Command Electronics 003-30 tail light gasket replacement. The new gaskets arrived but when I went to install them, I noticed the design of the light itself allows water into the back wall of the coach. The red plastic lens is not sealed to the black plastic body (the gasket seals the body to the coach) and rain is free to wash through the inside of the unit. This would not be an issue EXCEPT the bulbs mount from the bottom and there are holes for the wires to pass through and water is free to enter the coach wall there. Since the lens and back need to separate to replace bulbs, sealing the two together is not practical. May end up just buying better tail lights. Be far cheaper than rebuilding the back wall.

I know what you are talking about the foam rubber on mine leaked an the bulb shored out. When I replace my bulbs I used Prestite to create a seal, it stays soft and pliable and won't leak.
