A vehicle light which uses a laser light source device and has a shorter dimension in an optical axis direction than conventional vehicle lights. The vehicle light comprises a laser light source device and an optical system configured so as to form a predetermined light distribution pattern. The laser light source device includes: a cylindrical light-guiding part having a diffusing surface set in a region other than a light-introducing surface; a phosphor arranged in a light-emitting region on an outer circumferential surface of the light-guiding part; a reflective film arranged in a region of the light-guiding part other than the light-introducing surface and the light-emitting region; and a laser light source that outputs a laser beam which is introduced into the light-guiding part from the light-introducing surface and enters the phosphor. The light-guiding part and the laser light source are arranged adjacent to each other.
