Hello all,
Reversing lights packed up last night. Have checked both bulbs and are OK. Have also checked continuity of swith and me old tester beeps like a good un when reverse is selected, but doesn't give any reading for a voltage output. Fuse is OK. Could this still be the switch that is fooked or is there any common fault (there are so many....) I should look for?

Oh yes, what a t**t the reverse light switch is to get to on a TD4
