Abstract
A vehicular headlamp system and corresponding kit, including (left and right) headlamps and a mode switch (control mechanism) responsive to inputs from a mode switch console or other user interface arrangements, the combination of headlamps and mode switch providing high and low beam on-road illumination and a higher level of illumination for off-road illumination using the same light source in each headlamp as is used for the on-road illumination. Cooperation between a light source driver circuit in each headlamp and the mode switch results in the light source in each headlamp being driven by more or less current, as required by the selected mode. A (daytime) running lights mode of operation may also be provided using the same light source.
