The state-of-the-art in advance directional warning.
VPX SignalMaster™ traffic clearing light spotlights Federal Signal’s exclusive, high-intensity Viper® EXT modules. The VPX SignalMaster presents unparalleled levels of performance and reliability through a unique combination of advanced LEDs and reflector technology. 

The secret to superior LED illumination is a superior LED module.
Federal Signal’s exclusive Viper EXT modules are not only measurably brighter with the use of the industry’s brightest LEDs, but also spreads light more efficiently with its built-in Solaris® reflector design resulting in a substantial boost in light intensity and corresponding warning performance. Equipped with 4-, 6- or 8- EXT modules provide versatility to vehicle applications.
The fully-encapsulated, water resistant Viper EXT modules are engineered to provide extended service life for lower maintenance requirements. Additionally, the VPX SignalMaster’s extruded housing is specially design to block sunlight and glare that adversely affects warning performance and effectiveness.

Different applications call for different controllers.
The full-featured SignalMaster controller, sold-separately, operates with a low-power mode to reduce amp draw for nighttime operation and fast mode that increases the “build” speed of the warning pattern. Both the standard controller and the full-featured controller provide Left, Right, Center-Out and Flashing directional warning patterns.
