VEHICLE HEADLIGHT

A vehicle headlight () includes: a first light emitting optical system (LE) that emits first light (L); a second light emitting optical system (LE) that emits second light (L); a projection lens (); and a beam shaper (), in which the beam shaper () includes a main member () and a reinforcing member () overlapping the main member (), the main member () includes a base portion () having a part that includes a front end of the main member () and does not overlap the reinforcing member () and a part that overlaps the reinforcing member () and to which the reinforcing member () is fixed, and an upper surface of the base portion () reflects a part of the first light (L) toward the projection lens () in such a way as to form a cutoff line (CL) of a low beam light distribution pattern (PL).
