Reversing lights

Both Reversing lights not working, bulbs OK. Is there a separate fuse or is it shared? What number is it?
If not the fuse, I presume it's a connection to the gear box?

Hi Craig. Try disconnecting the switch at the gearbox, it's fairly easy to get to. Depending on corrosion, you might need a couple of plyers to pull the plug apart. Bridge the the plug (loom end) with a wire and see if they come on.
