An automatic headlamp dimmer system for switching a vehicle's headlamps from high beam to low beam when lights from another vehicle are detected in front of the vehicle. To prevent spurious responses to reflected light from signs and other sources, the dimmer system includes a light detector which is responsive only to infrared light. Also, unwanted responses to flashing lights are avoided by detecting the presence of a periodically varying light signal, and inhibiting switching between high and low beams in response thereto. The system is also capable of sensing the activation of windshield wipers and preventing headlamp switching caused by interruption of light to the system's light sensor by action of the wiper blades.
A system for automatically controlling the energization of the high beam headlamps of a vehicle in accordance with the presence or absence of light from the headlamps or taillamps of another vehicle, wherein the headlamps of the vehicle comprise conventional unfiltered incandescent lamps that emit light in the visible and infrared regions of the light spectrum, comprising:
