  • Two-wheeled vehicle lamp turn signal
    Patent number: 11952071
    Abstract: A first lamp unit and a second lamp unit arranged in a given direction are provided, luminous intensity of the second lamp unit in a lamp forward direction is set to be higher than luminous intensity of the first lamp unit in the lamp forward direction, and the first lamp unit and the second lamp unit are turned on sequentially with time difference. Thus, since the first lamp unit and the second lamp unit having different luminous intensity and being arranged in the given direction are turned on sequentially with time difference, it is visually recognized that emitted light flows from one side to the other, and the light is emitted from both the first lamp unit and the second lamp unit that has higher luminous intensity than that of the first lamp unit. Thus, it is possible to ensure high conspicuity in addition to improvement of functionality.
