A vehicular headlamp system (S) comprising: a pair of right and left headlamp units (12R; 12L) provided in a front end portion of a vehicle (V); and a road surface drawing unit provided in at least one of the pair of right and left headlamp units (12R; 12L), the road surface drawing unit being configured to emit first light (BR) so as to form a first light distribution pattern and to emit second light (BL) so as to form a second light distribution pattern such that a predetermined drawing pattern is drawn on a road surface on a front side relative to the vehicle (V) by the first light distribution pattern and the second light distribution pattern , the first light (BR) and the second light (BL) being set in a relationship of complementary colors, wherein the road surface drawing unit includes a first road surface drawing unit and a second road surface drawing unit provided in the pair of right and left headlamp units (12R; 12L), respectively; the road surface drawing unit is configured such that the first road surface drawing unit emits the first light (BR) so as to form the first light distribution pattern and the second road surface drawing unit emits the second light (BL) so as to form the second light distribution pattern ; the first light (BR) forming the first light distribution pattern is entirely a first color and the second light (BL) forming the second light distribution pattern is entirely a second color; characterized in that the drawing pattern is configured such that the first light distribution pattern and the second light distribution pattern are adjacent to each other or the first light distribution pattern and the second light distribution pattern are placed so as to partially overlap each other, the first light distribution pattern and the second light distribution pattern being in the relationship of complementary colors. a pair of right and left headlamp units (12R; 12L) provided in a front end portion of a vehicle (V); and a road surface drawing unit provided in at least one of the pair of right and left headlamp units (12R; 12L), the road surface drawing unit being configured to emit first light (BR) so as to form a first light distribution pattern and to emit second light (BL) so as to form a second light distribution pattern such that a predetermined drawing pattern is drawn on a road surface on a front side relative to the vehicle (V) by the first light distribution pattern and the second light distribution pattern , the first light (BR) and the second light (BL) being set in a relationship of complementary colors, wherein the road surface drawing unit includes a first road surface drawing unit and a second road surface drawing unit provided in the pair of right and left headlamp units (12R; 12L), respectively; the road surface drawing unit is configured such that the first road surface drawing unit emits the first light (BR) so as to form the first light distribution pattern and the second road surface drawing unit emits the second light (BL) so as to form the second light distribution pattern ; the first light (BR) forming the first light distribution pattern is entirely a first color and the second light (BL) forming the second light distribution pattern is entirely a second color; characterized in that the drawing pattern is configured such that the first light distribution pattern and the second light distribution pattern are adjacent to each other or the first light distribution pattern and the second light distribution pattern are placed so as to partially overlap each other, the first light distribution pattern and the second light distribution pattern being in the relationship of complementary colors. <EOS>
