2006 honda jazz has no reverse lights, have changed relevant fuses and both globes with no luck, where to from here, suggestions anyone otherwise i will have to take it to auto electrician for an $89 diagnostic, plus repairs

 

Check the reverse switch and wiring to/from it. It should be on top of the transmission, I think #8 here:

 

Have you tried changing a bulb? It’s not impossible both bulbs are out.
