PROBLEM TO BE SOLVED: To secure sufficient unexpectedness by a contrast between lights-out and lighting and an ample notifying function to a following vehicle, and to expand the latitude for free design. SOLUTION: At the center of the luminance range of plain lenses 4, 5, covering the front opening of lamp housings 8, 9, transparent function displays 4a, 5a are provided, respectively, of which color are identical with a luminous color of functional color luminous means 10, 11. When the light is out, the functional color of the function displays 4a, 5a, and the achromatic color of the function display surroundings 4b, 5b are recognized as two colors. When the light is on, the color of the function display surroundings 4b, 5b becomes also the functional color, which is recognized as one functional color resulting from expanded luminance range. Thus unexpectedness is produced.
