Hey guys, just wondering if I could get some suggestions. The brake lights on my GTA work when the car is parked, but when I'm stop at the end of my driveway, only the middle one comes on. I'm pretty sure that only the middle light come on when I'm out driving too. but park it, cut it off, and they all three work. What could cause this? Thanks.

the first place i would think to look would be the light sockets for loose or broken wires, that are only making contact sometimes

 

Or filled with water.
