driving home from band practice @ 10 @ night, i realize that it's a lil bit dark out. the headlights aren't on. the highbeams won't turn on. even the fog lamps won't turn on. the parking lights, the reverse lights and everything works. so, i checked all the fuses and they're fine. i pulled out the head lamps and they don't appear to be blown. now i'm at a loss. i don't know what to check. any advice out there would be greatly appreciated!
