I'm trying to find out if the mirror mounted turn signal indicator (W210 2000 E320) is a complete replacement module, if it's a simple bulb swap...or a full mirror shell replacement.

I've searched far & wide and can't find a module or a bulb, so I've finally decided to ask the guys that know.

Also, if it is the module or the bulb, does anyone have any idea where I can buy replacements?

Thanks in advance...

Its an array of 3 LEDs, nothing more and I have yet to see one fail, the usual reason of non working is corrossion on the connector that joins to it. its a slide on connector that engages as you push the cover and lock it into place.

My driver side one was not working, I removed it to find dirt/corrosion on the connector, cleaned it up and put some electric grease in there and its been working ever since (years).

You cannot buy that LED piece separately but it does come out from the shell, btw - if you want to know how to release the shell, its not like the early W210 - its got one locking spring in the middle which you push away rather than the wire clip of the old model.
