Abstract
For vehicles having left and right headlights, a steering direction signal input indicative of a left or right steering direction is used to modulate a control signal of a liquid crystal beam broadening device to broaden horizontally the vehicle headlight beam when the steering direction signal input is indicative of a selected one of a left or a right steering direction and to maintain or reduce a horizontal spread of the vehicle headlight beam when said steering direction signal input is indicative of one of a left or a right steering direction opposite to the selected steering direction.
