I've researched and purchased three sets of LED reverse lights over the years. The first set was awful, second set a bit better, and the third set is just ok. In the real world, I just don't think they provide me the expected light output I was looking for or the light is being scattered so badly it's not focused towards the rear. There are newer generations of reverse LED's with large heatsinks that I might eventually try.
I've put warm white LED's throughout the Cruiser, LED corner lights in the ARB, underhood COB LED's, LED bulbs in the Depos, LED puddle lights, and I was even planning on building my own rocklights with COB LED's or LED panels.
