Abstract
A system for controlling the turning on of vehicle headlamps,of a vehicle having a dome light,which provides a variable dome light intensity includes a sensor,, a memory,, a comparator,, and a circuit,. The sensor,senses the intensity of ambient light and provides a first signal &agr; indicative of the intensity of the ambient light. The memory,stores a light value &sgr; corresponding to the intensity of the dome light,. The comparator,receives the first signal &agr; a and compares the intensity of the ambient light with the stored light value &sgr;. The comparator,provides an output second signal &bgr; when the first signal is at or below the stored light value &sgr;. The circuit,turns on the vehicle headlamps,when the circuit,receives the output second signal &bgr;.
