Default Re: Brake light problem

First thing I would do is check your grounds. Sounds like when you step on the brake light the voltage is trying to backflow thru the running light instead of going to ground. Hence the running light goes out and the brake light does not light.

Try connecting a jumper wire from a known good ground (bumper, frame, etc,) to the light housing to check.

Bad grounds cause weird things to happen.
