Abstract
A low-beam headlight element includes a lens () for modifying the distribution pattern of light penetrating the lens, and a reflector element () including a first end having a place for a light source () and a second end having an opening constituting a passage for the light penetrating the lens. The thickness of the lens is shaped to decrease more strongly towards a first edge () of the lens than towards an opposite second edge of lens so as to provide more refractivity on a first area of the lens abutting on the first edge than on a second area of the lens abutting on the second edge. The refractivity on the first area produces a cutoff line in a resulting light distribution pattern. Hence, for achieving a cutoff line meandering in a desired way, there is no need for a screen element which converts light into heat.
