The Reliant light bar features a low-profile, linear design that provides a superior multi-color warning on vehicular applications. Designed with safety in mind, Reliant is packed with exclusive technologies and comes with various standard functions to cover all your basic needs at a budget-friendly price. Reliant includes (28) flash patterns, built-in SignalMaster, and alley, takedown, brake, and flood light capabilities to keep emergency personnel safe on the road.

SpectraLux® Lights The Way 
Exclusive to Federal Signal, the SpectraLux multi-color LED technology allows an LED light source to change color while in operation. In each module of the light bar, through user-selected flash patterns, the LEDs can change between Amber, Blue, Red and White (up to 2 in each module).

Solaris and ROC (Reliable Onboard Circuitry)
Built with Solaris LED reflector technology, the Reliant light bar is engineered to increase off-axis warning and maximize the LED light source to eliminate dark spots and increase visibility while on the road. ROC technology minimizes potential failure points in the light bar — replacing wires, connectors and assemblies with PCB assemblies to reduce labor repair time and increase road time for law enforcement personnel.

FS Convergence Network 
For maximum performance, the FS Convergence Network provides “plug-n-play” installation. Utilizing the RJ45 connections, the Reliant can be easily programmed using a Pathfinder light/siren controller. With control head programmability, the user can customize the keypad to meet their needs. 

A serial interface module (ordered separately) with your existing light controller can also be used to program and operate the features and functions of the Reliant.
