摘要

Improvements in the automatic change for lighting range in headlights of vehicles, such as automobiles, trucks and the like, characterized by the fact that a photoelectric cell located in an appropriate place at the front of the vehicle is provided, apt to receive the incidence of lights of another vehicle that goes in the opposite direction; said cell being arranged so that it does not function until it receives a precalculated power of light, and that it is studied in a manner that matches that power of the headlights of the other vehicle that, marching in the opposite direction, could dazzle the driver; being indifferent, to the effect, that the vehicle coming in the opposite direction has short-range lights or long-range lights; and when said photoelectric cell receives an adequate power of light, decreasing the resistance of said photoelectric cell, changes, directly, or through a transistor the conduction horn of a bistable multivibrator, which excites directly, or through a transistor preamplifier, to a power transistor that, in turn, drives a relay.
