To provide a luminous vest capable of expressing excellent preventive effects for traffic accidents by accepting and reflecting lights from vehicles and luminating without accepting lights from the vehicles in the evening or in the night by forming a light accumulating part, e.g. excellent preventive effects are expressed by luminating through accumulating lights from vehicles passing in front of a person wearing the vest and the sun light in the daytime in the light accumulating part.

In this luminous vest, which a policeman or a guide put on during a traffic control and a patrol guidance in the night, a horizontal belt-like reflecting part is formed around the waist part 2 of a vest body 1 and pairs of belt-like reflecting parts 4 are formed on the surfaces of the front part 1a and the rear part to have a V shape having distances between the pair of left and right parts to be narrower downward. Light accumulating parts 5 capable of accumulating accepted lights and luminating the accumulated lights are formed on the vest body 1.
