Can someone help me with how to remove the cover of the High Rear Brake Light inside of the hatchback (that houses the LED light) on a 2003 C230 Sport Coupe? There is no tab that I can see and I don't want to just pry it off in fear of breaking it. The cover buzzes and rattles, so I want to stuff the inside or edges with foam.


Thanks in advance,
Mark
