To provide a vehicular headlight device that can suppress a driver from overlooking a pedestrian even under an adverse condition such as the nighttime, and the nighttime and a rainy weather.SOLUTION: A vehicular headlight device 1 comprises a left-side light emission part (a left-side pattern emission lighting fixture 4L) provided at a left side of a vehicle 2 so as to emit light to a predetermined light distribution area 16 in the vehicle 2 in a first emission pattern in which bright areas a1 and dark areas a2 are alternately repeated, and a right-side light emission part (a right-side pattern emission lighting fixture 4R) provided at a right side of the vehicle 2 so as to emit light to the light distribution area 16 in a second emission pattern in which the bright areas and the dark areas are alternately repeated. In one aspect, the first emission pattern and the second emission pattern are the same emission patterns Pf. In the other aspect, the first emission pattern Pf1 is an emission pattern in which first bright areas a11 are lined up in parallel, and the second emission pattern Pf2 is an emission pattern in which second bright areas a12 crossing the first bright areas a11 are arranged in parallel.SELECTED DRAWING: Figure 2

    【課題】夜間や夜間でかつ雨天であるといった悪条件の下でも運転者による歩行者の見落としを改善できる車両用前照灯装置を提供すること。【解決手段】明領域a1と暗領域a2が交互に繰り返される第1の照射パターンで車両2における所定の配光領域16に光を照射するように車両2の左側に設けられた左側光照射部(左側パターン照射灯具4L)と、明領域と暗領域が交互に繰り返される第2の照射パターンで配光領域16に光を照射するように車両2の右側に設けられた右側光照射部(右側パターン照射灯具4R)と、を備えた車両用前照灯装置1。一態様では、第1の照射パターンおよび第2の照射パターンは、同一の照射パターンPfである。他の態様では、第1の照射パターンPf1は、第1の明領域a11が平行に並ぶような照射パターンであり、第2の照射パターンPf2は第1の明領域a11と交差する第2の明領域a12が平行に並ぶような照射パターンである。【選択図】図2
