I go to get in the car and drive away I come to a stop sign an the guy behind me says I don't have brake lights, the just center light in the window. And when I let off the breaks my brake lights come alive. I'm stumped to this as I'm not good at wiring anything but that's just how the car came. Tried the parking light switch on top of the steering wheel and switching my head lights on and off. I don't get it. Please help! 1997 Subaru impreza 1.8 coupe
