I did the same with my allroad. Made a huge difference.Have you guys and gals noticed that the back up lights in the Egg are not very bright? I really notice it when it is raining. It is very hard to see when you look at your side mirrors while backing up.
I put replacement LED bulbs into the stock bulb locations in the hatch. They are not very big. The stock bulb is a 921 i believe. Is the hatch the only location for the back up bulbs?
On my last SUV, a '95 Range Rover County LWB, I put a large floodlight on the rear of the expedition rack. That worked too.
