ABSTRACT:
A high intensity discharge lamp automotive headlamp system is provided for three different lighting functions. The headlamp system is a single unit that provides for low beam, high beam, and daylight running light (DRL) functions. Two optical components are used to easily and effectively switch between the different modes of operation. The first optical component is a shutter that selectively blocks a portion of the light beam output. Secondly, either a single lens or lens portions can be moved either within the light beam path or into the light beam path to alter the divergence.
