Abstract

Prior art vehicular lighting has difficulty ensuring that spectral colors caused by chromatic aberration from a lens are not noticeable. This invention is provided with a semiconductor light source () and a lens (). The lens () is constituted from an entrance face () and an exit face (). The entrance face () has two sections. An upper lens portion (U) forms a first partial light distribution pattern (P). A lower lens portion (D) forms a second partial light distribution pattern (P). The upper part of the upper lens portion (U) forms a top edge portion (PU) of the first partial light distribution pattern (P) having a cutoff line (CL). The upper part of the lower lens portion (D) forms a top edge portion (PU) of the second partial light distribution pattern (P) having a cutoff line (CL), overlapping with the top edge portion (PU) of the first partial light distribution pattern (P). This results in the invention being capable of ensuring that spectral colors caused by chromatic aberration from the lens () are not noticeable.
