Help! SID giving me brake light failure message, I installed new brake light switch and all bulbs. I am new to Saabs, so, when I start the car, all 3 lights are on, both outside lights on the rear and the third light above the rear windshield. When I step on the brakes, all 3 get brighter, is this normal? Also, with no key in the ignition, when I step on brake pedal, the headlights come on, but they are dim, is that normal? Please help me!
