Auxilliary reverse light project - Anyone have advice for drilling reflector lenses? Running wires?

Nice, Eric. Guess I'm not that original after all. :)

if you get a chance, check out these lights - they are 1000 raw lumens and have a very small housing. The hole is only 1-3/4", it fits in the housing easily, and you preserve the reflector functionality (it is on the lower half of the lens).

To be honest, I prefer the way you did yours, but I just don't have that level of fabrication skills.

From the package:

I’m sure those will look great!
 
I looked around and it seems like all of the wires to the rear bumper area come through the passenger compartment, so I'll follow this approach.
 
Are these bumper lens’ the same for both Land cruiser and LX570 for 08-15?
It doesn't appear to be the same part number. I do not know if they are compatible or not.

Here are the Toyota part numbers:
Land Cruiser Rear Bumper Lens (my 2013)
Reflector - Toyota (81480-60031)
Reflector - Toyota (81490-60041)

Post facelift (2016):
81490-60080
81480-60080

I looked up the LX570 parts on Lexuspartsnow.com

Pre 2012
Lexus Part No.: 81490-60020 REFLECTOR ASSY, REFLEX, LH
Lexus Part No.: 81480-60010 REFLECTOR ASSY, REFLEX, RH

2012-2015
Lexus Part No.: 81490-60060 LAMP ASSY, REAR FOG, L
Lexus Part No.: 81480-60050 LAMP ASSY, REAR FOG, R

Also, to close the loop. These lights are terrific. They are incredibly bright.

I'd also mention that I had to drill two holes in the back of the lens - one where the bulb would go in a ROW cruiser, and one outboard from there. I needed to do this so I could put the washer and nut on the back of the LED mount. The angle didn't work from the primary hole. I sealed the secondary hole with clear RTV and a plug (I had them kicking around the shop). I closed the primary hole where I ran the wire with a grommet.

I ended up running the wiring (sheathed two wire 16ga tinned marine wire) from the engine bay through the firewall grommet, behind the passenger footwell kick panel, under the front passenger door step trim, under the B pillar trim, under the rear passenger door step trim, up over the rear wheel well, and down through the same grommet that the rear wiring harness passes through the floor. This required disassembly of those trim parts, including the full rear panel, and the 2nd row and 3rd row seatbelt anchors.

From there, I ran it parallel with and forward of the rear crossmember, and terminated it with a Delphi connector, so the rear bumper can be removed for service. This plugged into a connector on the rear bumper that splits to both lights. I zip tied this harness to the reverse sensor harness inside the bumper.

I didn't do the temperature testing that I had planned to. I may do this later, but was past the point of no return once I tried to remove the original lenses and the studs pulled out destroying them (the nuts were corroded onto the posts). I opted to just move ahead with the replacements.

These are definitely a good option for very bright reverse lights if you want to avoid cutting/drilling into the bumper.

One note is that if you wanted to avoid all of the wiring that I did, you could just hook into the reverse light circuit. According to my research, there is a yellow wire in the 7 pin trailer harness that is the reverse light trigger. If you did this, the LEDs would come on every time you put the vehicle in reverse.

I wanted to have mine switched from my Switchpros (which means I can also control it from an app on my phone), and able to be turned on with the vehicle off (hooked to the auxilliary battery, and set up that way in the Switchpros). That way I can also use it as a scene light when setting up the camper.

I'm still debating about whether I want to have the Switchpros have a reverse light for a trigger wire. It is easy enough to do, if opt to go in that direction.
