Id start by checking for shorts between the ground side of your break lights (before the break light switch) and the ground for your interior lights. somehow power is bypassing your break switch which turns your break lights on/off when you hit the break pedal, it does this by controlling the ground side of the circuit.

When in doubt, power out!!!!!!
