PROBLEM TO BE SOLVED: To provide a vehicular backup light capable of suppressing occurrence of a dark portion in a front region on the road with respect to a vehicle rear end part.SOLUTION: A vehicular backup light includes: a light source 22 for emitting light downward; a reflection surface 28a for main light distribution provided below the light source 22, and for reflecting the light from the light source 22 toward the vehicle rear; a top surface reflection surface 28b provided at the backside above so as not to shield the light from the light source 22 entering the reflection surface 28a for main light distribution; an additional reflection surface 28c for reflecting at least one part of the light which does not enter the reflection surface 28a for main light distribution out of the light from the light source 22 toward the top surface reflection surface 28b; and a lens 26 in which the reflection light from the reflection surface 28a for main light distribution and the top surface reflection surface 28b transmits. It is constituted so that the light of the reflection surface 28a for main light distribution irradiates the place farther than the front region on a road R with respect to the vehicle rear end part, and the light of the additional reflection face 28c irradiates the front region.SELECTED DRAWING: Figure 3

    【課題】車両後端部に対する路面上の手前領域にダーク(暗部)が発生するのを抑制できる車両用後退灯具を提供する。【解決手段】下向きに光を出射する光源22と、光源22の下方に設けられ、光源22からの光を車両後方に向けて反射する主配光用反射面28aと、主配光用反射面28aに入射する光源22からの光を遮らないように、後方、かつ、上方に設けられた天面反射面28bと、光源22からの光のうち、主配光用反射面28aに入射しない光の少なくとも一部を天面反射面28bに向けて反射する付加反射面28cと、主配光用反射面28a及び天面反射面28bからの反射光が透過するレンズ26と、を備える。主配光用反射面28aの光が車両後端部に対する路面R上の手前領域より遠くを照射するように構成され、付加反射面28cの光が手前領域を照射するように構成されている。【選択図】図3
