A method and apparatus is used to rapidly modulate the intensity of a vehicular lamp for the purpose of enhancing the vehicle's conspicuity. A timer is used to generate a periodically varying pulse width modulated signal that is used to drive a transistor connected to one or more lamps. The modulation rate is chosen such that the lamp or lamps appear to flicker when seen with peripheral vision, yet appears not to flicker when seen out of the center of the eye.
