Check junction block underneath truck on frame...
Basically a harness connector using a bolt to connect many wires together.
Black and square with bolt to hold it together

Many many many threads on issues with lights and this is could be your issue...

The junction box is located in the passenger side rear fender area above the factory location for the exhaust pipe.

A well known spot for corrosion.

Alright will check it. And tell y’all if it worked or not. Cause I’ve light tested the fuses. And If it’s not this coming on to the reverse switch. Or a ground somewhere.
