I picked up a set of Rago MSPs for a significant discount since they weren't painted, which is exactly what I wanted since I was planning on doing some customization to them.

...you know me!
I fab'd up some metal brackets for a set of the same flash pattern amber LEDs I'm running behind my front grille, to provide side visibility and also made a pair of metal arms for amber LEDs facing rearward as well. The wiring for all 4 LED lights come together via simple anderson plugs and merge into a single red and black wire that run to the sPOD SE in the engine bay with a single touch screen button control to turn on and off.
After all the customization, I had them powder coated along with all the new brackets and hardware to really black them out. Also added a couple of Toyota OEM tie down hooks to the roof mounts - part # 58460-35012. A final touch was applying black rubber caps over all the nuts and studs for an ultra clean look and also prevents fabric snags and tears since there are some sharp edges there.
I then added molle pouches for things I'd want to grab regularly and quickly from the back window - flat tire repair kit, first aid, flash lights, knife, axe, shop towels, gloves, etc. I was careful not to block the entire rear passenger side window as I still want to see out of that window when backing out and parallel parking. I use the MSPs a ton and absolutely love them. My favorite interior mod by far.
