Federal Signal Exclusive Technologies Federal Signal is The Driving Force™ behind the technology that provides safe and reliable emergency warning for municipal, utility, tow & recovery and DOT vehicle.

Exclusive to Federal Signal, these innovative technologies help provide work zone safety.

SpectraLux® multicolor LED technology provides the ability for a LED lighthead to change color while in operation. LEDs can change between Amber, Blue, Red or White through user-selected flash patterns.

Solaris® LED reflector technology is engineered to increase off-axis warning and maximize the LED light source to eliminate dark spots and distribute 360-degrees of light coverage.

SLR (SOLARIS® LED ROTATOR) design maximized the LED light source for full light coverage. SLR rotates providing superior light functionality.

FS Convergence Network provides "plug-n-play" installation with Federal Signal's SmartSiren® Platinum, amplifier and controller, to the family of serial communication lightbars and the SpectraLux ILS interior lighting system.

ROC (Reliable Onboard Circuitry™) Technology eliminates approximately 85% of the connection failure points found in a typical lightbar. Wires, connections and assemblies are replaced by PCB assemblies - reducing labor repair time and increasing the road time for emergency vehicles.

HotFoot® lighted mounting feet provide additional light through powerful Solaris LED reflectors that are built into the mounting system of the lightbar.
