Whelen Justice 56-Inch Lightbar

Whelen Justice - 56"

Command the right-of-way for your largest fleet assets with the Whelen Justice 56-Inch Lightbar. Standard 48-inch lightbars often fall short on massive commercial chassis, failing to extend past the cab pillars and reducing off-axis visibility at intersections. The 56-inch Justice solves this. Designed specifically for heavy tow rigs, plow trucks, and massive rescue apparatus, this extended lightbar provides colossal 360-degree warning power. Built on a severe-duty extruded aluminum chassis, it features a highly modular design that allows fleet mechanics to swap out individual LED modules in the field without removing the entire bar from the vehicle.

Key Features & Upfitter Specs

Extended Fleet Coverage: The massive 56-inch length provides maximum off-axis intersection visibility for large commercial truck cabs, flatbeds, and heavy-duty chassis (F-450+).
Linear-LED Output: Features four high-intensity Linear-LED corner modules combined with highly customizable CON3 or LIN6 inboard modules, creating an unmistakable SAE Class 1 warning footprint.
Modular Serviceability: Engineered for extreme ease of maintenance; lightbar sections can be accessed by removing four screws to quickly swap lenses, upgrade modules, or change color configurations.
Extruded Aluminum Base: Built on a rugged, heavy-duty extruded aluminum platform that will not flex, warp, or crack under the intense off-road vibration of heavy diesel equipment.
Aerodynamic Profile: Measures just 2.25 inches tall, minimizing aerodynamic drag to preserve vehicle fuel efficiency and reduce wind noise inside the cabin during highway operations.
