Clear lenses and the absence of color in the lightbar produce an inconspicuous appearance. The lightbar can be controlled through any standard switch packs or siren/switch controls. Only 2.1" tall for less drag and increased fuel efficiency. Long-life LED X modules are all solid state. Powered through a standard 12V input. All voltage management handled at the lighthead through the integrated light engine and optics of the Torus module. Polycarbonate lenses and an extruded aluminum frame.
