Hi there. I'm new to MB World. Such a great repository of info and encouragement!! My question is a bit perplexing to me...why would the headlamps/tail lamps in my '91 560SEL come on completely on their own with doors locked etc.??? It has happened a few times over the past number of months where I will get up in the middle of the night and my car lights are shining (and, sadly it drains the battery). The last two mornings I've gotten up to the lights on...first day I caught it early enough that I was able to start the car but this morning I had to jump it. Could it be the headlamp relay? Or is there a common electrical gremlin that I haven't heard of? Any input is appreciated
