2008 diesel auto with no reverse lights

Hi all, sorry about asking as im sure its been covered but after searching the forum for 3 hours i still can’t find an answer.
So MOT guy informed me that I have no reverse lights! Its and Auto so not sure where the switch is located? Is it on the auto box or the CJB?
Parking sensors work fine.
Wing mirrors dip as expected.
R shows and stays on when Reverse is selected.
Both bulbs look good and did swap out.
Checked F5 and swapped 10A out but no change.

Any help with this is greatly appreciated.

Have plug in diag tool but show no errors that relate to lights. Crying or Very sad

They reverse lights are fed from a fuse in the battery box (16e) to the relay on the CJB. There is a 10 amp fuse 5 (CJB) which you need to take out and check. The other thing to check is whether you have a good earth to the bulbs. Take the bulbs out and apply 12v to them to see if they work. Could be faulty but dosen't show up.

Also check to see if you have power on the fuse when in reverse and ignition on.
