A headlight controller controls a headlight unit that illuminates a predetermined range in front of a vehicle. The headlight controller includes an inter-vehicle distance obtainer, an illumination controller, and a light distribution controller. The inter-vehicle distance obtainer acquires an inter-vehicle distance from the vehicle on which the headlight unit is mounted to a vehicle in front traveling in front of the vehicle. The light distribution controller partially dims or shades a range corresponding to a position of the vehicle in front, within an illumination range of a high beam. When the inter-vehicle distance is less than a first distance, the illumination controller displaces downward by a predetermined amount at least an illumination range of a low beam out of the illumination range of the low beam and the illumination range of the high beam by the headlight unit, regardless of operation of the light distribution controller.
