PROBLEM TO BE SOLVED: To provide a vehicular headlight that can form an optimal light-distribution pattern on for each country or each area with the fewer number of components in comparison with the conventional vehicular headlight, and a light guide lens used for the vehicular headlight.SOLUTION: A vehicular headlight includes a light source; and a light guide lens having at least a light-incident surface wherein light from the light source enters, a light-emitting surface, a first lens surface for transmitting the light from the light source entering from the light-incident surface, and a second lens surface for transmitting the light from the light source entering from the light-incident surface, on the surface. The first lens surface is a lens surface wherein a first reflection surface having a reflection surface shape on the basis of a surface shape of the first lens surface is formed, and is a reflection surface for forming a first light-distribution pattern. The second lens surface is a lens surface wherein a second reflection surface having a reflection surface shape on the basis of a surface shape of the second lens surface is selectively formed, and is a reflection surface for forming a second light-distribution pattern. |
