the brake light switch is bad.

Your brake lights are stuck on, either the switch is out of adjustment or bad. It is mounted on the brake pedal arm just under the dash.

I have the same problem. Currently I have the pedal strapped up to the steering wheel to keep it of the switch,preventing battery drain. Right now I have bigger fish to fry, replaceing all brakes and lines. Before she gets put back into service, I will have to address the issue.

Good luck to ya, I will be keep up w/ this thread.

Thanks guys!As usual,you are right on target.So,I ordered a new switch from LMC.
Now,how do I replace the switch when it comes in?It's a 1970 F-100 auto trans.I can't figure out how the switch mounts to the brake pedal and I don't want to break anything trying.........

unplug the wiring from the switch and unscrew the switch from the pedal bracket. unless it has been repaired using a couple of nuts. then unscrew the nuts and slide it out of the bracket.

Thanks.Much appreciated !!!! I think its stock as there were no screws/nuts/bolts around the switch unit.
