On our recent camping trip, I was in the bathroom and could smell something burning. There was smoke coming from the bathroom light fixture (one of the two thinlight fluorescent double bulbs, exterior mount type) I turned the light switch off, opened the bathroom vent and opened the fixture cover, took bulbs out and took off the white metal electrical cover. Smoke was coming from the ballast which is wrapped in clear plastic. Today I called Airstream, although the service rep said it was probably the ballast, he wasn't aware of any major issues/recalls with these fixtures. Our trailer is a 2002 Classic 25' with very little use in excellent shape. Has anyone else experienced or heard of simular problem? I'm going to replace the "problem" fixture for sure, do you think I should replace all the fluorescent fixtures?
