ABSTRACT:
An automatically slaved light for a motor vehicle comprises a roof mounted lamp steerable about a horizontal and vertical axis, and an internal control unit within the coach of the vehicle. The control unit rotates the lamp unit about the vertical axis via a first motor in the lamp housing when the vehicle is engaging a turn, wherein the lamp is rotated in the direction of turn of the vehicle to an angle proportional to the steering angle thereof as determined by a steering angle sensor coupled to the vehicle's steering wheel. The lamp is rotated upward about the horizontal axis by the control unit via a second motor in the lamp housing when the vehicle is traversing a declinate section of road, wherein the lamp unit is rotated upward relative the longitudinal axis of the motor vehicle to an angle proportional to the angle defined between the longitudinal axis of the vehicle and the gravitational horizon which is determined by a level sensor in the control unit.
