Front fog lamp bulbs

Front fog lamp

One of the front fog lamps on my SLK230 is not working, I have checked the bulb, the fuse and the wiring to the bulb with a continuity tester, and all is fine, so I am confused as to why the lamp will not work. If anybody has any idea, I would appreciate it.

Use a test lamp to diagnose your fault.
In theory you can use a continuity tester, but a test lamp will make the job much simpler.
