Provided is a vehicle headlight device including: a first light irradiator that irradiates light from a light source at a first magnification m1 in a form of a first radiation pattern in which a bright region and a dark region are alternately repeated; and a second light irradiator that irradiates light from a light source at a second magnification in a form of a second radiation pattern in which an entire region is a bright region. In the vehicle headlight device, directivity of the light radiated from the first light irradiator overlaps with directivity of the light radiated from the second light irradiator, and the first magnification m1 is smaller than the second magnification. Thus, it is possible to prevent or reduce failure to notice a pedestrian by a driver even under adverse conditions such as nighttime and rainy weather.
