92 300E.
Fuse looked good (#8 under hood) - replaced anyway. Left turn signal lights up. No current front or back to parking lights. On the taillight, the amber corner light works but the red parking light in the center of the assembly is what is not getting any current. Happened seemingly overnight. Any ideas? Light switch malfunction? (Why just left side though?)

 

I sometime have similar problem. The fuse is fine but it is
not making proper contact.

Take it out and put it back and see.

Regards

Syed
