Undoubtedly, st3303 PRO is at the top of the STEDI offer. A pure expression of capability and design that converges with brutal performance, making the all-new ST3303 PRO unmistakably STEDI. 
 Have we got your attention yet? Well it will  use a high performance, dual relay (yes dual relay!), dual fused wiring harness that is included. The current is so intense that the 60 LED bars have two separate power cords (yes two separate power cords!) on either side of the lightbar and two separate vents (yes, two!) to deal with the massive current draw.
