Standing a mere 2" tall, the Allegiant light bar is packed with Federal Signal exclusive technology and options to provide a superior multicolor warning. Designed to keep you safe on the road, the Allegiant includes 28 high performing, attention-getting flash patterns, built-in SignalMaster, and impressive flood light capabilities. Exclusive to Federal Signal, the SpectraLux multicolor LED technology provides the ability for a LED light source to change color while in operation. Built with Solaris LED reflector technology, the Allegiant light bar is engineered to significantly increase off-axis warning and maximize the LED light source. ROC technology minimizes potential failure points in the light bar — replacing wires, connectors, and assemblies with PCB assemblies to reduce labor repair time.
