Picked this up recently as some of you may have already seen on facebook. Rare Port Authority of NY/NJ vision slr From a a wrecker. Bar was never installed or put into service but was sitting around an upfitter for years. Whats interesting about this bar is that it is not serial controlled. Straight power and ground and the bar operates. Custom firmware installed and cannot be modified unless motherboard is reprogrammed by federal. according for fedsig only 17 were ever manufactured.
