Abstract

The disclosure provides for an automatic vehicle exterior light control system including an optical sensor and a processor. The processor is in communication with the optical sensor and a speed sensor. A light control subroutine may be activated in response to a control signal output by the processor in response to a plurality of conditions. The subroutine is activated in response determining that the speed of the vehicle is maintained between a first speed and a second speed and a detection of an external light from an external light source detected by the optical sensor. Once the light control subroutine is activated, the processor changes the light level of the light source from the first level to a second light level and maintains the second light level until the processor detects the vehicle speed exceeding a third speed.
