1. A vehicle headlight device comprising:
a low-beam lamp and a high-beam lamp that emit light into a first light distribution region that is in front of a vehicle; and
a patterned-light emitter that emits light into a second light distribution region in an illumination pattern in which bright regions and dark regions alternately repeat, the second light distribution region being further toward an outer side than the first light distribution region in a vehicle width direction, wherein
the patterned-light emitter emits light such that intervals between the bright regions are formed along an entire length of the illumination pattern in a traveling direction of the vehicle, and the intervals between the bright regions that are adjacent are wider at a position further ahead of the vehicle than at a position closer to the vehicle in the traveling direction of the vehicle.
