Abstract
A vehicle headlight of a small projector type can provide a favorable light distribution for an overhead sign area along with a light distribution used as a low beam. The headlight can include a semiconductor light source and a projector lens including first, second and third light-emitting surfaces. The headlight can project light having high brightness underneath a horizontal cut-off line while projecting other light in the downward direction using the first and third light-emitting surfaces. Additionally, the headlight can be configured to illuminate light having small chromatic aberration toward the overhead sign area using the second light-emitting surface located between the first and third light-emitting surfaces. Thus, the headlight can provide a favorable light distribution pattern used as a low beam and a favorable light distribution pattern for the overhead sign area using the light that color separation is inhibited so as to conform to a vehicular standard.
