Abstract
A system for adjusting the direction of a light beam from a headlamp assembly comprises a condenser lens which is movable along an arcuate path. As a vehicle turns a corner, the system moves the condenser lens along the arcuate path, so as to direct the light beam in the direction that the vehicle is moving. Because the condenser lens follows an arcuate path, the light beam is not distorted, allowing for greater angular displacement of the light beam.
