The brake light switch is mechanical, and operated
by the brake pedal. The switch may be damaged or its plunger sticking allowing a circuit between
the two wires. If you take off the wires and the lights go out it is the switch at fault.

brake light switch needs adjusting. if you look under the dashboard where the brake pedal is, its usually just above the pedal, it will have two wires connected to it. wind it towards the pedal, so that it pushes the plunger in on the switch it's self.
