That's exactly what mine looks like. What do you need a picture for?
The plastic backing has the guide so you know which is which and if you can't work it out from the picture, there's a reference table in the manual.
They look exactly the same to me. Have you swapped them with new ones/others that you know that work?
I'd suggest to check the fog light connections (it's notorious for coming loose) and the sidelights bulbs (they blow a lot).
