Federal Signal offers a wide variety of Headlight and Taillight flashers made especially for Police and non-Police vehicle applications. Our flashers feature solid-state reliability and customized brackets for the unique Police car applications such as the Ford® Police Interceptor® Utility, Chevrolet® Tahoe, and Dodge® Charger. Flash patterns are selectable on all models, except for the Tahoe. Other features include Low Voltage Protection, Reverse Polarity Protection, High-beam deactivation, and Night-time cut-off.

The FHL2-SC provides unsurpassed reliability and value in a relay-driven package. The FHL2-SC is an economical solution for those applications that do not utilize Police package vehicles.

Federal Signal’s taillight flasher is universal for most applications. The FHL-TAIL can be integrated into vehicles that do not have a vehicle integrated taillight flasher.
