Vehicular lighting
The objective of the invention is to provide vehicular lighting such that unevenness in the light distribution occurring on a road surface is minimized upon consideration of workability when performing an adjustment by aiming, or the like. This vehicular lighting forms a light distribution having a cut-off line CL, and comprises a light source (30) and a lens (50) disposed on the forward side of the light source (30). The entry surface (51) of the lens (50) wherefrom light from the light source (30) enters comprises: an upper side entry surface (54) on an upper side from the center of the entry surface (51), wherein first light diffusing portions (54a) for diffusing the light are disposed; a lower side entry surface (56) on a lower side from the center of the entry surface (51), wherein second light diffusing portions (56) for diffusing the light are disposed; and a middle entry surface (55) including the center of the entry surface, wherein third light diffusing portions (55b) and fourth light diffusing portions (55a) for diffusing the light are disposed, and having straight-through portions (55c) wherein no third light diffusing portions (55b) and no fourth light diffusing portions (55a) are disposed. The light diffusion width for each of the third light diffusing portions (55b) is larger than the light diffusion width for each of the fourth light diffusing portions (55a).
