After years of poor backup light illumination (even with the most potent LED bulbs I could find for the backup lights) I found this 54 watt LED light bar that fits absolutely perfectly in the under panel of the E53.

Mounted it today.
The hardest part was drilling holes in the stainless steel bracket
It's powered by the same relay output that isolates the camera from voltage fluctuations in the backup light circuit. The mounting bracket lays perfectly centered between two ribs in the under belly panel.
Understandably, not everyone is a fan of my rear camera mount and that's OK, it works for me.
It should really make visibility at night while baking up a real illuminating experience.
