You did have the ignition on when trying the reverse lights ? next check is switch on gearbox.
As a few members have pointed out it's probably the switch.HI all....
I've an old diesel, manual ' V ' reg and was giving her the once over for the MOT test today....
All looked OK ish apart from I have no reverse lights.....One bulb had blown and has been replaced the other was fine and tested OK....I've checked the Fuse in passenger foot well and its OK....But still no reversing lights....
Any ideas...Im stumped
Cheers Richard
Cheers.....and just for the record....You guys Rock......
As Peter says, if bulbs and fuse check out OK then almost certainly it is the switch, see this thread for more details.
