They look to be strictly cosmetic so making the costly investment in legitimate light bar seems kind of fruitless to me, but that's just my 2 cents. I'm also the one who wants to pull an additional 2/3rds the weight of the OBS in cargo/trailer haha.
If you want to put LED's surrounding the high and low beams like angel eyes, consult theretrofitsource. Typically they use fluorescent rings that are fastened around the projector shroud, as they look better since they are seamless since there are no gaps of light between individual diodes, but there are ways to do it with LED's. The downside to the fluorescent rings (CCFL ring) is that they're typically fairly fragile and if not supported well they can crack through regular driving.
