Abstract: In one illustrative example, a vehicular flasher unit is operative to provide a heartbeat flasher scheme in vehicle flasher lights. One illustrative technique in the vehicular flasher unit involves monitoring a flasher enable input to identify a flasher enable signal and producing, at a light illumination output in response to identifying the flasher enable signal, a heartbeat flashing scheme in the vehicle flasher lights. The heartbeat flashing scheme has a repeating sequence of two heartbeat pulse flashes in the vehicle flasher lights which include a first heartbeat pulse flash and a second heartbeat flash. Each first heartbeat pulse flash has a first peak intensity in the vehicle flasher lights and each second heartbeat pulse flash has a second peak intensity in the vehicle flasher lights that is preferably different from the first peak intensity.
Abstract: In one illustrative example, a vehicular flasher unit has control circuitry; memory which is accessible by the control circuitry and having a plurality of pulse width modulation (PWM) flasher scheme data sets stored therein which correspond to a plurality of flasher schemes for vehicle flasher lights of a vehicle; a flasher scheme selection input to the control circuitry; a flasher enable input to the control circuitry which enables a flasher scheme in the vehicular flasher lights; and a light illumination output from the control circuitry which controls illumination of the vehicle flasher lights.
