Rear brake light problem

A few months ago I placed the sequential lights on my GT CS. Everything works fine, but now I have a problem. When I am testing the lights (brake and turn signal) and the car is not running, everything works fine. When I am driving with the car the LH brake light won't work. Can someone explain why this is only whe I am driving with the car? Should it be a 'ground' problem??
I hope someonecan help me.

80% (I am told) of electrical problems can be traced to ground issues. Always the first place to start

I am having the exact same issue with my car. I replaced a very tired ground strap today, and cleaned as many dirty contacts as I could find, but to no avail. Any one else have this issue? Reiny - did your issue turn out to be a ground problem?
