Abstract
Abstract A headlight device comprising a main reflective mirror associated with a main light source, an auxiliary light source mounted adjacent to one side edge of the main reflective mirror, and a lens covering the front side of the two light sources. The one side edge of the main reflective mirror is formed and located such that the light emitted from the auxiliary light source toward the main reflective mirror is not shielded by the one side edge of the main reflective mirror so that the light emitted from the auxiliary light source is irradiated through at least a substantial part of the reflective mirror. The part being located remote from the auxiliary light source.
