Abstract: A vehicle headlamp device to be applied to a vehicle includes a light source and a lens. The light source configured to emit illumination light. The illumination light is to pass through the lens. The lens includes an illumination light converging portion configured to, when a part of the illumination light passes through the illumination light converging portion, converge the part of the illumination light. The illumination light converging portion is provided in a region through which high-beam illumination light emitted from the light source passes. The illumination light converged by the illumination light converging portion is used as marking light at an optical axis adjustment that is performed during manufacturing of the vehicle.

Abstract: A vehicle headlamp device to be applied to a vehicle includes a light source, a lens, and a controller. The light source is configured to emit light. Light emitted from the light source is to pass through the lens. The controller is configured to control light distribution patterns for the light. The light distribution patterns include at least a first light distribution pattern and a second light distribution pattern. The first light distribution pattern illuminates an area ahead of the vehicle during running of the vehicle. The second light distribution pattern is projected as a marking at an optical axis adjustment that is performed during manufacturing of the vehicle. The controller causes a part of the light source to emit light so that the second light distribution pattern is formed.
