PROBLEM TO BE SOLVED: To provide a technology improving visibility of a vehicular lighting tool.SOLUTION: A vehicular lighting tool 200 according to one embodiment includes: an LED light source 18; a laser beam source whose luminance is higher than the LED light source 18 and irradiation area is narrower than the LED light source; and an optical system that forms a light distribution pattern with light emitted from the LED light source 18 and laser beam source. The LED light source 18 and the optical system may be constituted so as to form a light distribution pattern for passing-by beam. The laser beam source and the optical system may be constituted so as to form a high-luminance area being in the vicinity of the central part of a light distribution pattern and having a cutoff line. |
