I got the idea on this board. I wanted something different than the typical LED strip across the back tailgate, so I picked up two Whelen model PSR00XRR Striplites and added them as supplementary Brake/Turn/Tail lights.
I have thought about doing the same. I have a 14 RAM with the Whelen HALO brake/warning lights. Don't know if adding the strip lights would be overkill.
Your addition Looks good though.
