Claims

[Scope of utility model registration request]

A vehicle headlamp comprising a bulb provided with a main filament, a subfilament, and a light shield, a reflector that reflects light from the bulb forward, and a lens that refracts the light reflected from the reflector, wherein the bulb an aperture provided in the center of a light shielding body, a means for transferring a light distribution pattern of a part that causes glare of the light flux exposed from the aperture to a light distribution pattern of a part that does not cause glare, and a drive for driving the transfer means. A vehicle headlamp characterized by comprising means.
