Dipped headlight`s light beam switching method for motor vehicle, involves automatically performing light beam switching for passing from one light beam to another light beam if spot speed of vehicle exceeds threshold value

摘要

The method involves measuring a spot speed of a motor vehicle, and comparing the spot speed with a threshold value to determine whether the vehicle is moving in a town or on a motorway. A light beam switching is automatically performed for passing from one light beam to another light beam if the spot speed exceeds the threshold value, where the threshold value is equal to forty kilometers per hour.
