What might be wrong with a Mitsubishi Galant if the lights only turn on when the driver hits the breaks?
Are you talking about ALL the lights, or just the dash lights? If it is just the dash lights, you might have a bad ground for the dash electronics, or bad connection at the Dash Dimmer control. But if you are talking about headlights, too, check the gound wires on the battery... perhaps wiggle them around until the lights flash. The brake light switch should not do this. It only controls the back lights. if its only the dash lights lighting up when you hit the brake, check the brake bulbs and make sure that they are the correct bulbs. (dual filament) and that the base of the bulbs contacts arent touching
