Abstract
To vary the angle at which the headlight beams are directed only road surface from within the passenger compartment of a moving vehicle, spring forces urging hinged headlight mounting frames foreward are matched by the force of a spring assisting a winder to urge, via a first cable, lever, second and third cables, the frames in the opposite direction such that the force required to move the frames in either direction via a knob in the passenger compartment is substantially that required to move the frames if they were hanging or otherwise under the influence of only their own weight.
