Reliant® S2 Light Bar

Federal Signal's ultra low-profile Reliant® S2 light bar is designed to provide superior LED warning at a budget-friendly price. The Reliant S2 features tri-color capability,  FSJoin® technology, and a pre-curved extrusion to prevent bowing to ensure optimal light bar performance.

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. Through the use of user-selectable flash patterns, LEDs can change between Amber, Blue, Green, Red, and White.

Solaris® and ROC (Reliable Onboard Circuitry™)

Built with Solaris LED reflector technology, the Reliant S2 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 work truck personnel.

FS Convergence Network 

For maximum performance, the FS Convergence Network provides plug-and-play installation. Utilizing the RJ45 connections, the Reliant S2 can be easily programmed using a Four-button Convergence Network controller.  

FSJoin Technolgy: Enhancing Compatibility and Customization

FSJoin is a programming compatibility feature integrated into Federal Signal's light bars, warning lights, sirens, and controllers. This advanced technology offers users a highly customizable visual and audible vehicle warning system. It enables the synchronization of functions, operations, and flash patterns across individual light heads from multiple warning devices, creating a cohesive vehicle solution when paired with a Convergence Network siren or controller.

Using the Convergence Network Configuration Software, you can program each light head to perform a variety of functions. Beyond synching the Reliant S2 with other FSJoin-compatible products and creating custom flash patterns, the software allows for extensive programming options including:

• Create separate color modes
• Choose specific modules for takedowns, alley lights, work lights, cruise, flood, SignalMaster, brake*, reverse*, and turn signals* 
• Program flash rates for individual modules
