Probably the reverse switch that is located on your transmission.... Stick or auto and what year.... If its a stick with the ZF6 then its a discontinued item however Corvette Central remade them.... Just bought one a couple months ago and it works great.

Looks like you answered that question while I was "thinking"!



Here's the switch.

the system is pretty simple. take an electric tester to se if juice is getting to the lights. If not, then check so see if its getting to the out side of the switch. If not, then check to see if its getting to the intake side of the switch. If not, check to see if its getting to the out side run from the fuse...if not, then check to see if its getting to the in side run to the fuse...you starting to see a pattern here? Oh, while near the switch, check by hand to mafe sure its moving enough to turn on the lights. Start from the back and work forward..half the battle is finding what is NOT wrong.

Interesting! What exactly is the purpose of this switch?

You say to check it to see if its moving enough? When you put it in reverse, does it not send an electrical surge to tell the car it's in reverse, or is it actually a moving part?

The switch has a rod in it with a ball end that rides against a shifter shaft inside the trans. That shaft has a depression in it that the ball end falls into when you shift into reverse and closes the switch for the backup lights. Mine was not working for a little while, but before I got a chance to change the switch, I changed the trans oil to AmsOil manual syncromesh. About three days later after driving it for a while, the switch started working again. I guess there was something in the new oil that 'un-stuck' the switch!

The switch isn't the easiest to remove but if a person had some patience yes removing it and cleaning the ball end of the switch might actually restore it to an operational state. Before removing and considering it "at fault" you of course need to confirm that there is 12V to the connector, you can then confirm it from the switch also if it's operational. I'd clean the connector end with contact cleaner while there.
