does clk 500 2006 side markers have a fuse? if yes where is it located
it is not listed on the diagram

replaced the light with 2 new bulbs and still doesnt work
is it a burnt fuse ?

I would doubt there would be a dedicated fuse for the side markers.

Check if other lighting is not working and check that fuse.

Often, the socket is corroded due to moisture. Even though they both do not work (my assumption), they may have stopped working at different times due to corrosion. If corroded you can try maybe wd40 and a small brush or just replace the sockets.

None of the exterior lights are fused. They are electronically controlled by the SAMs. On those side markers, a common problem is corrosion in the socket.
