Weird electrical problem

Hi

Few days ago while my wife was driving the car a message came up on I-drive screen 'Reversing right light failure' I thought a bulb has blown up so I changed with brand new bulb but still I got message 'Reversing right light failure' and light doesn't work.I tried same bulb on my left rear light and it worked,so the problem obviously is not the bulb?Later on I found out whole rear right (picture below) light doesn't work so I swapped rear right light panel with rear left light panel to make sure the problem is not in rear right light panel it didn't work.I tested the voltage on the rear right light 11V, I checked fuses everything is OK .Can someone explaing why this light doesn't work?

Thank you

You checked voltage. Did you check ground?

Yeah check ground, and make sure no bare wires are exposed causing a short.
