Hi there, that's what I'm fitting, RDX Multifunction units, stop, tail and reverse in the main larger housing and the reflector in the smaller upper housing,
I spent a long time trying all sorts I'd lens combinations and configurations and decided upon needing 2 sizes with the smallest at the top to he most aesthetically pleasing, then I varied the diameters of the circles for best fit and form, as it happened the largest looked best at 95mm so I could use the same type I used in my quantum, whereas the smallest needed to be around 60-65mm to look best
and I couldn't find any other lights to fit that also didn't have ridiculously convex lenses so opted to put the reflectors there as I found some 67mm units that also light up with tail.
The fog and reverse will be relocated to the bumper in separate units.
