LED Reverse/ Backup lights in rear bumper step cavity?

That's gotta be the best way to go right there. I'm definitely doing it that way when I get mine

Yeah I thought that was the easiest way to go.  My truck already had the factory LED bed light kit that comes with 2 lights mounted near the rear of the bed and tied into the factory switch below the HVAC controls.  I wanted a little more bed light plus a little light in the step cavities to see them at night.  I just bought another factory bed light set off ebay and spliced them into the existing harnesses in the bed then bought 2 of these:

and mounted them in the roof of the step cavity and spliced into the same wires (I wanted a softer glow so I wired some resistors inline before the bullet lights -- you can get them from Oznium too).  When I use the factory cargo light switch on the dash the cargo light, all 4 bed lights, and both step cavity lights come on with no problems.  And since they are tied into the factory wiring they will automatically shut off before the battery drains too low.

Do you remember which wires are for the bed lights? And where did you splice into them at?

Mine came from the factory with the first set of bed lights already installed so the wires were already there.

 

If you buy the factory kit it comes with all the wiring you need and a plug that fits into a junction box just behind the spare tire.  Search these forums and you will find threads with part numbers and pictures.

Has anybody found a way to override the cargo light switch inside the cab so the bed/cargo lights dont go off when the truck is in drive?

I was thinking same thing

I went with the smaller ones, simple bolt-on design and tapped into the reverse lights. Hardly noticeable and give off quite a bit of light, I'm happy with them. Got mine from the website, wish.com.

I installed 1 led light in each bumper step. I drilled a hole in the center of the step toward the top. Right behind your hitch are a bunch of wires and plugs. I connected both wires to one of the wires that works with the cargo lights and grounded out the others. I forgot which one it was but ill look tomorrow. It works perfect. Never had a problem. I added some pictures below.

Check out the tow mirror adaptation write up by Pgamboa (within this site) - 1st page he has a diode fix. All cargo lights stay on when in reverse

While this doesn't directly address adding extra lights to the back of the truck, this simple modification will cast quite a bit of light toward the back of the truck along the sides.

 

By adding a single wire to the BCM under the dash on the driver's side (at least in the 2016 and 2018 HD trucks) you can get the side mirror cargo lights to turn on whenever the truck is in reverse (when the truck is running) or the cargo light switch is turned on (when the truck is turned off).

 

You need to run a wire from pin connector 26 on the Brown BCM block to pin connector 25 on the Pink BCM block (see picture).

 

Following are some pictures of the amount of light put out with this mod.
