Stoplights are usually turned on by a switch mounted above the brake
pedal. When the pedal is fully released, it presses on the switch and
it breaks the circuit. When you press the pedal, it releases the switch
and the circuit completes, turning on the lights.
Most likely cause of this is that the switch is either broken or misaligned.
Adjust the switch to be depressed when the pedal is up. If the lights turn off, you're done.
If
this does not fix it, unplug the switch from the wiring harness. If
this makes the lights go off, your switch is broken, buy a new one. If
it does not, you have a short circuit in the wiring. You will need to
trace the harness, find the damage and repair it by splicing or
replacing the harness.

Check the brake-pedal switch. This small button behind the brake pedals is activated when you press down on the brake pedal and makes the brake
light go on. Press the switch by hand to see if it's stuck. If it is,
pressing it may force the stuck part.
