The internet seems totally silent on the proper way to change the door mirror puddle lights on an L322, so here ya go. First off, you do not pry it out from under the door mirror, that'll break the plastic lens. To do it properly, adjust the mirrors so they're facing inward as much as possible. That will expose a little hidden slot to insert a screw driver into to release the clip on the light. Voila. Easy peasy and no breakage.

 

Great now I have to go see if I have mirror lights😂
