PURPOSE:To provide a vehicle lighting fixture with good appearance having no inconvenience such as the lighting of an area laid along the upper and lower side edge parts of an outer lens and causing no snacks eye phenomenon. CONSTITUTION:Within a transversely long lamp chamber space having a wide cross width, compared with the longitudinal width, which is formed of a lamp body 10 and an outer lens 12, a light source 14 is received, and an inner lens 16 is disposed between the outer lens 12 and the light source 4. A diffusion step 13 is formed on the outer lens 12, and a Fresnel step 17 is formed in the area just opposite to the light source 14 of the inner lens 16, and prism steps 18 are formed on the side parts of the Fresnel step-formed area. In such a vehicle lighting fixture, the prism steps 18 are formed on the upper and lower side edge parts of the area just opposite to the light source 14 of the inner lens 16 to reduce the longitudinal width of the Fresnel step-formed area 16a, and light shielding parts 20 for shielding the light directing diffusion step non- formed areas 13a laid along the upper and lower side walls of the outer lens front surface are extended and formed on the upper and lower side walls 11a, 11b of a lamp body.
