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 for police applications. For example, this mini-light bar can be used as a primary warning device on off-road vehicles used for security and patrol or as wing lights on law enforcement vans.

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 increase visibility while on the road. In addition, 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 Wires, connectors, and assemblies have been replaced by PCB assemblies—reducing labor repair time and increasing the road time for vehicles.

Features Made for the Job 
The 21" Allegiant can be configured specifically to fit your needs. It comes equipped with (28) high-performing selectable flash patterns and a low power mode for added visibility. 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.
