ABSTRACT:
A projection headlamp system for a vehicle includes a high beam subsystem and a low beam subsystem. Each of the high and low beam subsystems includes a pair of light pattern projecting arrangements, a remote single arc discharge light source, a pair of solid optical coupling devices, and a pair of elongated light distributing conductors coupled at output ends to the pair of light pattern projecting arrangements and coupled at input ends to the pair of solid optical coupling devices. The high and low beam subsystems employ either separate single arc discharge light sources or a common single arc discharge light source.
