I have a 2015 JK and found the reverse lights to be very poor for ligthing up the area behind you at night.
After some searching I found some nice ideas on how to install additional reverse lights and decided to make my own.
I bought a set of these MicTuning 4" 18W LED bars on Amazon and designed a bracket in Sketchup.
I also replaced the original reverse light bulbs with LED versions, to reduce the total current when adding the light bars.
I think I will have sufficient light now when reversing. ;)
The Sketchup file is also attached.
