Abstract
A light assembly comprises a fixed mounting plate on which there is positioned a variable resistor, a rotatable member including an arm engaging the variable resistor and a lamp subassembly pivotally mounted to the rotatable member and keyed to the rotatable member such when the lamp subassembly is rotated in a plane generally parallel to a lens associated with the lamp subassembly, the rotatable member moves with respect to the fixed mounting plate, thereby varying the resistance, which is coupled in series with a lamp contained within the lamp subassembly for varying the intensity of the illumination therefrom. In a preferred embodiment also, the lamp subassembly includes a lens having a knob associated therewith such that the lamp subassembly can be tilted and rotated for directing and varying the intensity of the illumination therefrom.
