I mounted back up lights in the new Aluminess rear bumper today. I don't have them wired yet so I don't know how bright they will be. These are the lights I ordered.

They were the brightest 4" X 6" light I could find. Hella has 3 different beam patterns in this series of work lights to choose from. I ordered the long range beam light.
They come stock with 2 55W H3 bulbs in each light. I purchased 100w bulbs to replace the 55W'ers but I am a little concerned about heat so I'm going to run with the 55W bulbs for a while.
The lights didn't fit in the bumper very well due to the lights thickness. I ended up adding a 3/4" shim between the bumper and the light to center the light up and down. I'm a little limited with the ability to aim the lights outward. The edge of the light is very close to the bumper. I think the lights Aluminess sells for back up lights sit farther inside the bumper and don't have the clearance issues.
