A vehicle headlamp (1) includes a light source unit (11, 11A, 11B) having semiconductor light emitting devices (13) and a lower reflector (14, 14A, 14B) disposed below the semiconductor light emitting devices (13), and a projection lens (17) configured to project light emitted by the semiconductor light emitting devices (13). A portion of the light reflected by the lower reflector (14, 14A, 14B) and projected by the projection lens (17) forms a pattern (T1) of an upper portion of a high beam high beam light distribution pattern (P1). Auxiliary pattern forming means is provided for forming, when at least one of the semiconductor light emitting devices (13) forming a laterally central portion of the high beam light distribution pattern (P1) is turned off, an auxiliary pattern (T2, T3, T4) irradiating at least a part of a region that would otherwise be irradiated by an upper portion of the central portion of the high beam light distribution pattern (P1) formed by the at least one of the semiconductor light emitting devices (13). |
