Federal Signal - Allegiant Max - Video

Built for demanding work truck applications, the Allegiant® Max is a low-profile, linear LED light bar designed to deliver high-output visibility and rugged durability where it matters most. Whether you're operating in construction zones, utility work sites, or roadside response environments, Allegiant Max ensures your fleet is seen—and safe.

Unmatched Visibility in Every Direction

Featuring Federal Signal’s exclusive SpectraLux® multi-color LED technology, Allegiant Max allows up to three colors per module—Amber, Blue, Green, Red, and White—offering flexible response modes for multi-purpose fleets. Integrated Solaris® LED reflectors and built-in SignalMaster™ directional warning provide bright, consistent off-axis illumination to cut through low light, dust, and weather.

Smart Features for Smarter Operations

The Allegiant Max goes beyond lighting. Optional ambient light sensors automatically dim lights in low-light conditions to minimize glare. Integrated sync functionality lets like-programmed vehicles unify flash patterns via GPS—critical for coordinated fleet safety. Alley ground lights and rollback safety reflectors enhance operator awareness when exiting the vehicle or working roadside.

Built for Fast Installs and Long Shifts

Compatible with the FS Convergence Network, Allegiant Max offers plug-and-play setup with RJ45 connectors. Easily serviceable without removing from the rooftop, this light bar simplifies fleet maintenance. A full range of mounting options and lengths—from 45' to 80'—makes it a fit for nearly any work truck configuration.

Tested and Trusted to Perform

Certified to SAE J595 Class 1, SAE J845 Class 1, CCR Title 13, and IP65-rated for weather resistance, the Allegiant Max is ready for daily abuse in high-risk environments. Backed by a five-year warranty and supported by Federal Signal’s fleet experts.
