SClass Side Mirror

I scratched the wall with the right side mirror of the car. Nothing happend but the signal light plasitc cover on the side mirrior broke.
does any one know if i need to replace the whole side mirror or can MB change the lights only (or the cover)?
by the way the lights are working fine its just the plastic transparent cover
