I have factory lights and one 60" light shorted out. After that light was disconnected, the other 6 lights worked fine. When I contacted the dealer (still under warranty) they found out there was a recall. Sounded like one of those if you had a problem, they would fix, but if the warranty run out first, you would never hear about it.
Anyway, Fleetwood sent me a complete set of seven new lights, so I'm set for a while. When we get some good weather I'll get it put on.
Yours could be the lights, or power to the lights. Are you sure they are all on when they come on? If they are off, check for voltage at the source wire.
