Suited for undercover and highway vehicle applications, the SpectraLux ILS by Federal Signal offers the same advanced warning and directional lighting as a full-size lightbar. This interior lighting system features Federal Signal's SpectraLux multi-color LED capability. While in operation, a single LED light source can change color combinations, including red, amber, blue, and white. From inside the vehicle, the low-profile SpectraLux ILS blends into the headliner of the vehicle. When illuminated, white LED options can be used as takedowns, work lights, or act as a flood light. Rear models operate as a standard emergency warning or SignalMaster directional warning for oncoming traffic.
