I looked at the shovel mount. I decided to fabricate my own, I think I can make it look a little less bulky.
The lower bumper lights are flush mount 24W LED. I had to cut a 3" square in the plastic bumper cover to sink the assemblies into. Between the lamps and bumper cover I layered some foam to smooth the edges and fill the small gap. Behind the bumper cover I fashioned a steel square into which the lamp is secured. However, I did not consider the curvature of the bumper cover and should have bent the bracket slightly before installation to prevent deforming the plastic. The wires I ran up to the tail lamp body harness, there I soldered in my own pigtail to the reverse light power and ground with the corresponding connector on the new bumper lamps. In total, I think it took about 45 minutes to install and cost about $35
The roof mounts I used 1/8" steel, cut and TIG welded using AUTOCAD (automotive - cardboard aided design) then just primed and painted. I could fabricate custom ones for you if you'd like. Private message me and we can discuss what you are looking for in a mount, and you can send me some dimensions and sketches.
