Most likely a bad ground or fuse, letting it backfeed thru the bulbs. My grandpa's truck recently acted up like that. Everytime he pressed the brakes his dome light would come on which was really odd. And his brake lights were'nt working. He changed a fuse and checked a ground and got it working. Ive also heard that a bad bulb can make stuff act funny like that? Like a tail light burnt out making both quit working??? Thats what ive heard.
