one time i thought my overhead light was burnt out, but someone pressed the button labeled "room" and it came on.
fact is, lights burn out. especially old ones. i find it odd that so many of yours have gone, while only one of mine is out (def).
however, i did notice today that my front left parking light is dim, and i have never hit any fences. its just one of those things to be replaced.
if this continues and is apparently breaking down, get it looked at.
does the pass. door lock have a light too?
