Abstract

An automatic headlight switching procedure for motor vehicles, designed to emit a beam of light from one lighting mode to another lighting mode. The process features the steps of when the headlights are in a first lighting mode, detecting the backscatter of the headlight beam onto a phenomenon of visibility disturbance; increasing the lighting range of the headlight beam in relation to a maximum authorized range in accordance with the detected backscatter; and switching the headlights to a second lighting mode when the backscatter is below a first determined threshold.
