clean bulb sockets with some 800 grit sandpaper.

Yeah probably the unit sunlit mentioned, I had mine come out of alignment before.
The easiest way to tell, does your truck start in "N"??

your gear indicator indicates those readings? chuck it for a new delco one if adjusting it does not help.

your welcome.

I have a similar issue. No reverse lights.
Difference is my transmission indications are correct, including the engine only starting in park and neutral.
Could it be the same cause?

More then likely not.

Possibly. The switch contacts can still break. They are on separate contacts in the switch. But follow the fuse power to each connector, switch or socket downstream to find the fault.

I would like to use that information you posted Sunlit, but the pictures. Every time I visit this thread I see a different set of pictures. Right now it's a serpentine layout for something, a 5-speed trans, and some other stuff. Earlier I'm pretty sure it was some Corolla stuff and random wiring diagrams. Yesterday, a family picture, no joke.
What switches should I check for these lights?

Yeah I still have a few posts like that running around here. BTW, family picture? Know nothing about that. I sent you a message regarding the switch.

I fixed my lights. After replacing the switch with the instructions provided by Sunlit I still didn't have lights. My logic was, both back up lights wouldn't burn out at the same time. To make sure I pulled the turn light bulbs out and switched them with the reverse lights.
************.
Both bulbs had burned out. What are the chances of that? So, now I have a brand new $50 neutral/park switch which works no better than the old and a new set of $10 bulbs, which were the problem in the first place.

Sorry about the revival of a dead thread but i'm having a similar issue.
The difference is when I put it in reverse the volt meter/amp gauge goes way down to around 9. Only happens in reverse and worked fine a few days ago.
Would it be the switch on the trans like SunlitComet said before? Thanks for the help guys, just looking for a place to start really.
I replaced the battery and the bolts/connectors already as well as a body to frame ground

on fuse #20 turn/b-u light and test the power on both sides of fuse. they should match if you have current system voltage there but it drops to 9 volt on the other side of the switch that it is likely the switch or corrosion somewhere. but even then if that voltage got to the bulbs you would think you would at least see them very dim. where do you see this 9 volts and can you disconnect the harness underneath the rear and test it there and at the switch? the rear disconnect is on the left frame rail to the left of spare tire if a 4-dr and the circuit is a light green wire.

btw any glitches with the neutral safety function?

I see the 9 volts at the instrument cluster. I forgot to mention that I bought the Tahoe with trailer wiring that had scotch locks on it and he used the large white wire for a ground. I fixed that and soldered/spliced a new ground by the connector I believe you are talking about.
I have no light emitting form the back up light. I have not checked voltage at the bulb connector yet tho.
Thank you for your help. It appears as though I may have bought someones electrical nightmare
