R170 sidelights

[stu99]

Tonight I noticed that one of the sidelights had gone in the SLK.

First I checked the bulb which looked OK but after putting it back, I noticed both sidelights were out of operation. I figured that maybe the fuse had gone but I couldn't locate a sidelight fuse in the fusebox -what would it be labelled as?

All other lights (including head and talilights are working normally). Any suggestions on what to try next?

Thanks for any info.

Fuse 3 is for one side and 4 for the other in the light fuse box RHD,,,you cannot see if a bilb is good or bad by looking at it
