I did not confirm but a salesman told me the wiring is in the bed even if the light is not there. Like I said a salesman said this so take it with a small grain of salt but worth checking into. If it is already there im sure you could buy the lights and add it.

I assume it is the same as what the corvettes have had for several years as an option with the butterfly valve that opens under hard acceleration to make the exhaust louder. There may be a fuse somewhere you can pull that will leave it open.

79,000 and 250 hours on my 05 Yukon. Mine reset also.
