To provide a vehicular lighting fixture capable of illuminating an overall emission surface in different colors without providing the same number of light sources of different colors.SOLUTION: A vehicular lighting fixture 10 includes: an inner lens 11 having a lens incident surface 21 and a lens emission surface 22; a light guide body 12 having a light guide emission surface 31, a first light guide incident surface 32, and a second light guide incident surface 33, which extends in a longitudinal direction along the lens incident surface 21; a plurality of first light sources 13 provided opposed to the first light guide incident surface 32; and a second light source 14 provided opposed to the second light guide incident surface 33. The light guide emission surface 31 is provided opposed to the lens incident surface 21, the first light guide incident surface 32 is provided on a side opposite to the light guide emission surface 31 in the light guide body 12, and the second light guide incident surface 33 is provided at the end part in the longitudinal direction of the light guide body 12.SELECTED DRAWING: Figure 1 【課題】異なる色の光源を同じ数だけ設けることなく、出射面の全体を異なる色で光らせることのできる車両用灯具を提供する。【解決手段】レンズ入射面２１とレンズ出射面２２とを有するインナーレンズ１１と、導光出射面３１と第１導光入射面３２と第２導光入射面３３とを有し、レンズ入射面２１に沿って長尺方向に延びる導光体１２と、第１導光入射面３２に対向して設けられた複数の第１光源１３と、第２導光入射面３３に対向して設けられた第２光源１４と、を備える車両用灯具１０である。導光出射面３１は、レンズ入射面２１に対向して設けられ、第１導光入射面３２は、導光体１２において導光出射面３１とは反対側に設けられ、第２導光入射面３３は、導光体１２の長尺方向の端部に設けられている。【選択図】図１
