My warning light started flashing that the ....tail light L visit workshop and ......the tail light R visit workshop and ....then the tail light R using back up light. I checked all the bulbs and they are sound. Whats the deal with the light? Any ideas? Its an 01 C320.
Thank you!

 

The sensors will pick up any variation in voltage. I had a issue with a plate bulb and a side marker both did the same. The plate bulb eventually went out so the service rep told me the sensor will give you a heads up when the bulb is going to burn out.

 

Okay, I will replace them and see if that doesn't help. Thanks!

 

Replace your bulbs!
