Abstract
A lamp unit includes a first light source; a projection lens that forms a light distribution pattern using light radiated from the first light source; a second light source; and a parabola optical system reflector that reflects light radiated from the second light source. The projection lens has a paraxial outer peripheral portion that is closer to a first optical axis than at least part of another outer peripheral portion as seen in the direction of the first optical axis. The parabola optical system reflector reflects light radiated from the second light source such that the reflected light passes through a space adjacent to the paraxial outer peripheral portion.
