Toyota Repair: no reverse lights, toyota camry, manual transmission

Question
I have a 2000 Toyota Camry 4-cylinder, manual transmission and both reverse lights not working.  All other lights, including panel lights working fine.  Is there a fuse for just the reverse lights and where is it located.  If not the fuse then what next.  Thanks.

Answer
Have both bulbs been replaced, if not that would be the first step, if they have been replaced then there is obviously another problem, the circuit is supplied with voltage through the "gauge" fuse located at the lower left of the dash under the plstic cover.
