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.
