The das light that indicates a burned out light bulb is on but there are no bulbs that are burned out. It comes on when I switch the parking lights on.

 

Did you just check the bulbs if anything is burned out or if any isn't lit up. We had the same problem with one of the tail light bulbs and it was a contact issue. The bulb would intermittently light up so we had hard time catching it. Check for lose wires or lose bulbs.

 

that there are 2 bulbs for each tail light. One of the two was out. My bad.

 

Ha! .... that is exactly what was bad on ours too but in our case the bulb was lose with intermittent connect. Glad you too got it!
