thaks but i took joe drivers advise and run new lights from the third brake lite.. works good.. thank you

As the m/f switch gets worse, you will start to lose parking/running lights, interior lights, and blinkers. That trick is a band-aid at best. You'd be better off fixing the problem switch before you get in an accident because someone didn't see you.
