Features

Federal Signal’s SpectraLux® Viper® S2 and Viper® S2 provide superior light output, and the easy pattern synchronization advances lighting expectations to a higher plateau. Exceptional warning capability, multiple model configurations, versatile mounting and simple product functionality make the SpectraLux Viper S2 and Viper S2 stand out as the best internal warning light in the industry.

Built-In Versatility
The Viper S2 and SpectraLux Viper S2 are ideal for dash/deck, headliner, and window mount applications, but can be installed almost anywhere inside the emergency vehicle. The housing is compact and made of lightweight polycarbonate which is safer in case of accident or air bag deployment. Mounting the Viper S2 and SpectraLux Viper S2 is made quick and versatile with a swivel type bail bracket and suction cups. Each unit comes equipped with a snap-on flash guard (no screws required) and reflective tape to help optimize forward LED light output. All models are shipped complete with flash guard, reflective tape, bracket and mounting hardware. Wire harness lengths are five feet long with synchronized units and nine feet long with cigarette plug units.

Reflective Light Output
Bold Blocks of light and superior off-axis reflection are achieved using advanced Solaris technology. Molded scalloped facets at the rear of the reflector direct LED light forward to form an impressive block of illumination. Two inboard side reflectors mirror high intensity LED light to the side producing wide-angle off axis warning. LED combinations include Amber, Blue, Red, and White.

Easy Push Button Pattern Selection and Multi-Head Synchronization
SpectraLux™ Viper® S2 and Viper® S2 lights are available in single- or dual-head configurations and are available with a cigarette plug or wire leads that allow for synchronization. Synchronized units use an advanced two-phase wire technology that coordinates flash patterns between up to eight lights at once, and the light patterns can be set to work as either concurrent flash or opposite flash. The simple to use, multi-purpose push-button pattern switch is used to scroll forward and backward through patterns and also to synchronize the light heads.
Viper S2 single units have 23 patterns, and dual units have 25 flash patterns. SpectraLux Viper S2 single units have 25-patterns, and dual units have 37 flash patterns.

SpectraLux Viper S2
Federal Signal’s popular Viper S2 interior warning light is available with SpectraLux multicolor LED capability that delivers dramatic light output and can be mounted almost anywhere inside the emergency vehicle. SpectraLux multicolor LED technology is available in combinations of Amber, Blue, Red, and White, and this technology provides the White LED “Takedown” feature. While still having the same design and build of the Viper S2, the advanced Solaris LED reflector combined with SpectraLux LED technology of the SpectraLux Viper S2 further enhances off-axis reflection, offers bolder blocks of light, and an intensified wide-angle off axis warning.
