Abstract
A system is provided having a controller for controlling operation of warning devices mounted on a vehicle for providing warning signals directed external of the vehicle. The controller receives one or more vehicle event signals, each indicative of occurrence of a different vehicle event. The controller responsive to receiving each vehicle event signal overrides operation of one or more of the warning devices from a normal operating mode into an override operating mode in accordance with the vehicle event associated with the vehicle event signal being received. In an override operating mode, warning device(s) may provide visual signals to supplement pre-existing vehicular light indicators of vehicle events, while other warning device(s) may be disabled to avoid confusion with such vehicular light indicators. To facilitate ease of connection, each warning device couples to the controller at an output port for receiving power and ground, and control signals from the controller.
