I was told my passenger brake light is working intermittently. Coming off an a highway rolling on to the exit, a gentlemen rolled down his window and informed me passenger brake light was out. On the road to get to work (where i am now) I have to traverse a railroad crossing. Its a moderate bump. Got to work and after asking the security guard, he said the light lit up fine. Backing in into a parking space he drove his little golf cart over to me and said, yep its out now. I know ZIP about electrical stuff in cars, any idea where to start before i throw money at a garage?

 

I would put a new bulb in it.
