A vehicle headlamp system comprising: a plurality of light sources (52R1 to 52R5, 52L1 to 52L5) for headlamps, configured to be provided in a vehicle, the plurality of light sources (52R1 to 52R5, 52L1 to 52L5) including a first light sources group (52R1 to 52R5) provided in a right headlamp which is configured to be disposed on a right side of the vehicle, and a second light sources group (52L1 to 52L5) provided in a left headlamp which is configured to be disposed on a left side of the vehicle; and control means for controlling irradiation of light from the plurality of light sources (52R1 to 52R5, 52L1 to 52L5) to form a light distribution pattern including a plurality of subregions (PA1 to PA5), each of which two or more corresponding light sources of the plurality of light sources (52R1 to 52R5, 52L1 to 52L5) can irradiate, characterized in that when the control means executes such control that a non-irradiation region is moved in the light distribution pattern, the control means turns on two or more of the light sources (52R1 to 52R5, 52L1 to 52L5) corresponding to one of the plurality of subregions (PA1 to PA5) that was before the movement an non-irradiation subregion, with a first time difference to irradiate the corresponding subregion after the movement, the two or more of the light sources (52R1 to 52R5, 52L1 to 52L5) irradiating the subregion that becomes an irradiation subregion after the movement includes at least one of the light sources (52R1 to 52R5) of the first light sources group (52R1 to 52R5), and at least one of the light sources (52L1 to 52L5) of the second light sources group (52L1 to 52L5). a plurality of light sources (52R1 to 52R5, 52L1 to 52L5) for headlamps, configured to be provided in a vehicle, the plurality of light sources (52R1 to 52R5, 52L1 to 52L5) including a first light sources group (52R1 to 52R5) provided in a right headlamp which is configured to be disposed on a right side of the vehicle, and a second light sources group (52L1 to 52L5) provided in a left headlamp which is configured to be disposed on a left side of the vehicle; and a first light sources group (52R1 to 52R5) provided in a right headlamp which is configured to be disposed on a right side of the vehicle, and a second light sources group (52L1 to 52L5) provided in a left headlamp which is configured to be disposed on a left side of the vehicle; and control means for controlling irradiation of light from the plurality of light sources (52R1 to 52R5, 52L1 to 52L5) to form a light distribution pattern including a plurality of subregions (PA1 to PA5), each of which two or more corresponding light sources of the plurality of light sources (52R1 to 52R5, 52L1 to 52L5) can irradiate, characterized in that when the control means executes such control that a non-irradiation region is moved in the light distribution pattern, the control means turns on two or more of the light sources (52R1 to 52R5, 52L1 to 52L5) corresponding to one of the plurality of subregions (PA1 to PA5) that was before the movement an non-irradiation subregion, with a first time difference to irradiate the corresponding subregion after the movement, the two or more of the light sources (52R1 to 52R5, 52L1 to 52L5) irradiating the subregion that becomes an irradiation subregion after the movement includes at least one of the light sources (52R1 to 52R5) of the first light sources group (52R1 to 52R5), and at least one of the light sources (52L1 to 52L5) of the second light sources group (52L1 to 52L5). at least one of the light sources (52R1 to 52R5) of the first light sources group (52R1 to 52R5), and at least one of the light sources (52L1 to 52L5) of the second light sources group (52L1 to 52L5).
