PROBLEM TO BE SOLVED: To simply enhance relative central luminance of a light distribution pattern for passing by.SOLUTION: A headlamp 1 for a vehicle individually forms a light distribution pattern Pfor passing by and a traveling light distribution patter Pformed by superimposing the upper light distribution Pabove a horizontal line H on the light distribution pattern Pfor passing by, in front of the vehicle. The headlamp 1 for the vehicle comprises: a first light source 21 for forming the light distribution pattern Pfor passing by; a second light source 31 for forming the upper light distribution P; a first lighting circuit 22 and a second lighting circuit 32 for controlling lighting of the first light source 21 and the second light source 31. The first lighting circuit 22 reduces light intensity of the first light source 21 more than when independently forming the light distribution pattern Pfor passing by when forming the traveling light distribution pattern P. |
