The LEDs in the driver-side mirror turn signal on my E320 are very dim. Any idea on what is causing this? The other side works fine.

You could try removing each cover & plugging them in the other side & see if the same cover that is dim is still dim on the other side.

I was thinking about that but didn't know if the covers were interchangeable between sides. I will try it today. Thanks!

The problem was with the LED assembly. Got a new one and all is well. Thanks, mbdoc, for the help
