Liberty™ SW WeCan® Series Super-LED®

WeCan Programmable Series includes an external interface unit, the WeCan® electronic control module (ECM), which communicates all lightbar operating functions via a 2 conductor, 20 gauge cable. All functions are programmed by a PC via simple “pick & click, or drag” screens. Windows® based 2000, XP or later operating system required. USB input to the ECM from PC or laptop makes programming easy.
