Whenever I put my 2002 Cadillac sls in drive with the lights on, a red light begins blinking in the reflection of my rear view mirror (it is one of the 3 lights above the inside of the back window). If I drive without the lights on, the red light does not blink. If I have the car in park without the lights on, the light does not blink. What is goin on?
