Are you talking about the led strip going across the front top of your fiberglass cap? Mine flickers on and off and when on is very dim. I was hoping to find an answer here as to how big a hornets nest it would be to try and replace or if anyone else had that problem and what fixed it. I haven't gotten the ladder out to see how the wire was run but looking at my friends 5th wheel (different brand), It looks like a hole with the power wire running thru it and then a glob of silicone to keep the water out.
