To provide a vehicular lighting device capable of efficiently guiding light at each light guide for guiding light from a plurality of light sources, while saving installation space.SOLUTION: A vehicular lighting device 1 includes a plurality of light sources 11, 12 arranged at one side of inner side or outer side in a vehicle lateral direction, and a plurality of light guides 21, 22 for guiding light from each of the light sources 11, 12 to the other side of inside or outside in the vehicle lateral direction and emitting the light to outside of the vehicle. The light guides 21, 22 include guide units 210, 220 and outgoing units 212, 222. Light paths from the light sources 11, 12 to guide units 210, 220 of the light guides 21, 22 and to the outgoing units 212, 222 are positioned on the same plane which includes light axis of each of the light sources 11, 12. Each of the outgoing units 212, 222 on light guides 21, 22 is arranged without overlapping in a vehicle longitudinal direction and with mutual offset in the vehicle lateral direction.SELECTED DRAWING: Figure 2 【課題】設置スペースの省スペース化を図ると共に、複数の各光源からの光を導光する各導光体において、光を効率的に導光することができる車両用灯火器を提供する。【解決手段】車両用灯火器１は、車両幅方向の内側と外側の一方に配置される複数の光源１１、１２と、各光源１１、１２からの光を車両幅方向の内側と外側の他方に向けて導光して車両の外方に照射する複数の導光体２１、２２とを備える。導光体２１、２２は、ガイド部２１０、２２０と出射部２１２、２２２とを有する。各光源１１、１２から各導光体２１、２２のガイド部２１０、２２０及び出射部２１２、２２２に至る光路は、各光源１１、１２の光軸を含む同一平面上に位置する。各導光体２１、２２における各々の出射部２１２、２２２は、車両前後方向に重ならずに車両幅方向に互いにずれて配置される。【選択図】図２
