Brake light wont shut off.

I have heard, as seems to be indicative on mine, that my brake light stays on because I need new brakes. The rear drums are very worn. It will only go off if while driving I hit the brakes a bit hard. Under hard accel, it will kick the light back on again.

Is it possible you may need a brake job?

Chris, i can see where UMD was coming from - i thought you were talking about the moron light on the dash too (till your last post).

so the issue is the stop lamp switch (on the brake pedal arm). if in doubt, just get a new one. the contacts get funky and can work intermittantly (think of how many times that switch has been used over the years). they cant be much money and are cake to swap. sounds like you switch was staying closed - that would not be cool to have happen while driving or overnight (dead battery, burned out bulbs, etc).

good luck Chris.

oh yeah, you still thinking of swapping your guts into another stang? i would not - sure is a sweet lookin ride!

There might be an issue with your brake light switch pad. A small bush kind of thing which presses against the switch under your brake pedal. Once broken the switch remains on and hence the lights stay on. It happened with my Stang and it seems Ford does not provide just that small part as aftermarket product and the only solution they provide is to change the whole brake pedal system which will cost you a fortune. Coming to the solution, which i adopted was to buy any 'KIA' or "hyundai' brake light switch pad which might cost you 3$ at max. They are the exact same size and very easy to install.
