PROBLEM TO BE SOLVED: To provide a less-expensive vehicular lighting unit capable of performing a sequential display.SOLUTION: This invention relates to a vehicular lighting unit in which three or more light sources are lit up in sequence or turned off in sequence to perform a sequential display, and there are provided the prescribed three or more light sources arranged in a forward or rearward direction of a vehicle and light guide bodies for guiding light from the light sources to emit the light frontward or rearward of the vehicle. The light guide bodies have three or more incidence elements oppositely arranged against each of the prescribed three or more light sources making the lights emitted from the light sources into primary parallel lights in parallel with a direction crossing at a right angle with an arranging directions of the light sources; a reflection part reflecting at an inner surface the prescribed parallel lights to make them into secondary parallel lights, an outgoing plane extending in a lateral direction of the vehicle to emit the secondary parallel lights. A plane length of the outgoing plane as seen from a top plan view is longer than a distance between the light sources positioned at both ends of the prescribed three or more light sources as seen from the plan view.SELECTED DRAWING: Figure 2

    【課題】シーケンシャル表示させることができる安価な車両用灯具の提供を目的とする。【解決手段】3以上の光源を順次点灯又は順次消灯させることでシーケンシャル表示する車両用灯具であって、車両の前後方向に沿って配列された前記3以上の光源と、前記光源からの光を導光して車両の前方又は後方に出射する導光体と、を備え、前記導光体は、前記3以上の光源にそれぞれ対向して配置され前記光源から出射された光を前記光源の配列方向と直交する方向に平行な一次平行光とする3以上の入射素子と、前記一次平行光を内面反射して二次平行光とする反射部と、車両の左右方向に延び前記二次平行光を出射する出射面と、を有し、平面視における前記出射面の表面長さは、平面視における前記3以上の光源のうち両端に位置する光源同士の距離より長い、車両用灯具。【選択図】図2
