Abstract: A vehicular wireless signal controller to work in an emergency warning system is provided that is simultaneously operable through a control head or a remote. The vehicular wireless signal controller includes a remote, a control head, a remote receiver and a control unit. The driver in pursuit or high speed chase situation because of emergent duty or timing wants to operate the emergency signaling system, he or she may needs to look for the control head. As a result, the driver can't mind his or her road's condition and it may cause accidents easily. A remote can be mounted on the top of turning axis of the steering wheel's shaft where is very close to the driver's hands holding with to improve the operability of the signaling system and reduce hazardous situation while in use with emergency vehicles.

Abstract: An emergency signaling system with integrated load management functionality is provided wherein the load management circuitry is alternatively operable in programming and operating modes. The system includes a keypad, control head, control unit and a plurality of signaling features selectively activated by the control unit in the operating mode. The load management circuitry automatically sheds loads from the signaling system in response to an indication from the electrical system powering the signaling system that an energy drain is occurring at the energy source that will cause disruption to other more important systems—e.g., the ignition system in a vehicle.
