2024 SLT here and I have the same problem.
The backup lights are horrible on these trucks.
They are unserviceable LED's. There are no bulbs that you can upgrade.
I really don't want to add any aftermarket pod lights to my brand new truck. Nor do I want to tee tap into any factory wiring.
You have to be careful with wiring into the trailer receptacle wiring. If you have the factory trailer app, it might think that a trailer is connected.
I guess it would be OK if you use a relay, using the 7 pin reverse wire to switch the relay and the 7 pin constant power from the trailer connector to feed the lights.
I was thinking of adding one of those tailgate strip lights, but I don't know if it would fit in that space under the tailgate. Then I would still have the problem of what to wire it to.
I was hoping someone here has solved this problem.
