Police Fire/EMS Work Truck

Federal Signal is excited to announce that multiple exterior and interior warning lights feature FSJoin™ technology. FSJoin is a programming compatibility feature of Federal Signal’s light bars and exterior/interior warning lights that work in conjunction with the Pathfinder® light/siren controller.

The combination of FSJoin warning lights and the Pathfinder siren allows the Pathfinder to control lights around the vehicle by utilizing flash patterns in the siren, syncing/alternating light heads, and dimming light heads.
