A headlight apparatus (12) for a vehicle (10) and a method of controlling the headlight apparatus (12) are provided. The headlight apparatus (12) includes headlights (20R,20L) which are arranged in the vehicle (10), each headlight (20R,20L) projecting light in multiple distribution patterns; and a control unit (18) which controls the headlights (20R,20L) based on a distance (X) from the vehicle (10) to an in-front vehicle. If the distance (X) is smaller than a threshold value (L), the control unit (18) controls a position of a first light distribution pattern (PL) to gradually move the position toward a horizontal line (H) based on the distance (X), and if the distance (X) is greater than the threshold value (L), the control unit (18) forms a second light distribution pattern (PH) that illuminates a region including a portion above the horizontal line (H), and controls an illuminance of the second pattern (PH). Alternatively, the headlamp (20R,20L) apparatus may include a rotatable shade (146) which is rotated to produce the light distribution patterns (PH,PL).
