Abstract
A novel headlight system which vertically re-aims at least a low beam illuminator to meet regulatory requirements, depending upon the mode of operation of the headlight system, while providing efficient and effective illumination.
Claims8
A headlight system, each side of the headlight system comprising:
- a low beam illuminator being horizontally and vertically aimable;
- a high beam illuminator;
- an actuator operable to alter the vertical aim of the low beam illuminator;
- and
- the system including a control means operating the actuator for each side to aim the low beam illuminator at a first vertical aim target position when the headlight system is operating in low beam mode and operating to aim the low beam illuminator at a second vertical aim target position when the headlight system is operating in high beam mode wherein both the high beam and low beam illuminators are operating.

The headlight system of claim I wherein the low beam illuminator includes a parabolic reflector.
A headlight system comprising:
- a low beam illuminator having a low beam hot spot;
- a high beam illuminator having a high beam hot spot;
- an actuator operable to alter aiming of the low beam hot spot;
- and
- a controller operating the actuator to move the low beam illuminator aiming the low beam hot spot at a first target when the headlight system is operating in a low beam mode wherein only said low beam illuminator is energized and operating to move the low beam illuminator aiming the low beam hot spot at a second target when the headlight system is operating in a high beam mode wherein both the high beam and low beam illuminators are energized.
