Abstract
A motor vehicle headlight includes a first, generally concave, reflector and a lamp mounted in the first reflector, the lamp connectable to a light source. A second reflector is housed within the concavity of the first reflector. The second reflector is moveable between a first position, wherein the headlight reflects a wide beam, and a second position, wherein the headlight reflects a narrow beam. The second reflector may be in communication with a device responsive to the speed of the vehicle in which the headlight is mounted, and accordingly, the position of the second reflector may be based on the speed of the vehicle.
