Abstract
Vehicle headlights that rotate in accordance with movement of the vehicle's steering system are disclosed. The rotatable lights are portable and suited for attachment on a variety of vehicles. The lights are rotated by means of small DC motors wired to a mechanical linkage mounted on the vehicle's steering column. The amount of rotation is determined by potentiometers mounted on the mechanical linkage and the DC motors. A logic circuit is also disclosed for use in conjunction with the device to enable each unit to be readily used on vehicles having different steering ratios.
