Redesigned from the inside out, experience the new Vision® SLR from Federal Signal. It is obvious as soon as you see the Vision SLR that it was engineered for safety. The distinct non-linear shape and exclusive Solaris SLR (Solaris LED Rotating Reflector) provide a maximum of 360-degrees of light output not achieved by a linear lightbar. Vision SLR maximizes light output to help clear the roadway in critical traffic intersections. Proudly made in University Park, IL.
