I get that error message periodically, but it never remains on after I restart the car. I think it refers to the driver's side front turn signal bulb, but I have noticed that the bulb is working normally, but the audible blinking sound is going at double speed. I didn't think about it meaning my driver's side mirror light...

Thanks for the reply.
In my case, I do see my driver side mirror does not lit up as goog as the left side one. But the strange part is, Some time it lit up good and the sign doesn't come. Do you think, it may be due to a loose connection? If so, how to open it?

Noticed same symptom after car wash

Did you recently wash your car?
I got the same issue after a wash.

I speculate it is either (1) side mirror seal or (2) just some loose connection.
Either way, you can follow instruction (with pictures!!) on how to open the housing & the assembly from these threads (thanks to kenstudios ).
It also has part # for the side mirrow seal.

I think I'd have an MB pro look at it. They can tell you in an instant what it is and how much it would cost to repair. If more than you want to pay, then follow the above suggestions. Personally, I wouldn't start digging around in there.
