Abstract
Abstract The headlights of an automotive vehicle are provided with wipers having elongated flexible wiping elements which are reciprocable along the outer sides of the respective lenses toward and away from a parking position in which they are concealed behind the moulding rings of the headlights. Sprinklers are provided to spray water onto the lenses, at least during a portion of reciprocatory movement of the wiping elements. The operation of the drives for the wiping elements and of pumps for the sprinklers is regulated by electric programming circuits.
