Mercedes-Benz E-Class W211 - Replacing rear brake lamp - PeterJW

I consider myself, with senior years, to have a good basic knowledge of dealing with replacing general parts on the various cars that I've owned. But I confess I'm 'stumped'. Can someone explain how you replace the rear brake bulb on a 2002 Mercedes E270 CDI.

On some of these,the brake light is an led cluster and can only be replaced as a complete assembly.
