Built for Versatility and Performance 
The Federal Signal 21" Allegiant is a low-profile dual-color mini-light bar solution that provides a superior warning signal to promote work zone safety.  Meeting SAE Class 1 and CAC standards, the 21" Allegiant is ideal for a variety of applications including DOT, municipal, utility, construction and tow and recovery vehicles. The 21" Allegiant can be used as a primary warning device or it can be used as wing lights on large work truck applications including rotator tow trucks and guzzler trucks.
Packed with Technology to Keep you Safe
Through the Federal Signal Solaris® LED reflector technology, the 21" Allegiant mini-light bar is engineered to significantly increase off-axis warning and maximize the LED light source to eliminate dark spots and to increase visibility while on the road and in work zones. The patented ROC (Reliable Onboard Circuitry™) technology is built to minimize potential failure points in the light bar. Wires, connectors, and assemblies have been replaced by PCB assemblies—reducing labor repair time and increasing the road time for work trucks.
Features Made for the Job 
The 21" Allegiant light bar is available in-stock models or it can be configured specifically to fit your needs.  It comes equipped with (28) high performing selectable flash patterns and low power mode. For added visibility in work zones, the 21" Allegiant offers optional takedowns and work lights features.  Additionally, the 21" Allegiant light bar features the exclusive bed light option which shines a steady work light down from the light bar onto the bed of the truck for added operator visibility.
