cracked the turn signal glass on the side mirror. on 2008 Mercedes-Benz S550

Approximately how much will this cost? It is not the actual mirror but the turn signal.

Asked by for the 2008 Mercedes-Benz S550
some of the lenses are replaceable seperate from the cover.If that is the type that you have it is about $210.00 for parts and labor.We would need a vin number to see if that is what type you have.
Thanks for your help
