I searched the forum but didn't find an answer...
Is there a fuse for the backup lights, or is the NSS the only point of failure short of a wiring problem (assuming BOTH bulbs havent failed at the same time!)?
I've looked at a fuse panel diagram but it doesn't list one for the backup lights.
If you are missing both of your backup lights, I'd suspect the neutral safety switch. Any of the other NSS symptoms like having to wiggle the shift lever to get it to turn over, or have to start in neutral?

ooooorrrr when your NSS leaves you stranded in a parking lot far away from home with little to no money with no one around you can go on your smart phone, look up the connector diagram for the NSS harness, cut up a old cell fone charger for the wires, use a nail clipper to strip the harness back and jump the 2 black wires in the harness to get her runnin again!.....not that ive had to do this or anything.......

I'm sure the back-up lights run through a fuse, and if the related wiring rubs against body sheet metal long enough it can short out and blow the fuse. I don't see the specific fuse mentioned in my panel documentation either though.
I'm inclined to agree with the other fellows however, that the NSS turns out to be the cause for lack of back-up lights more often than anything. The starter functionality runs through a second set of contacts that seems to last a bit longer before needing cleaning. An easy way to verify which is the problem would be to unplug the NSS connection at the fireway by the tranny dipstick and use a paperclip to make a temporary jumper in the harness side receptacle. If the lights come on with the jumper in place, the problem is in the NSS. If you decide to clean and service it yourself, take your time and be careful in removing since its plastic housing can be very fragile.
Connect your back-up lights test jumper as indicated here.
