Vehicle light fixture
A vehicle light fixture include a first light distribution illuminator that emits a first light distribution to the front of a vehicle, and a second light distribution illuminator that emits a second light distribution having a light-dark boundary line at least on a side of the vehicle, wherein illumination of the first light distribution illuminator and the second light distribution illuminator is controlled in response to a predetermined operation of the first light distribution illuminator by the driver of the vehicle. The second light distribution illuminator includes a light source, and a projection lens that projects light emitted from the light source to form an illumination pattern surrounded by multiple light-dark boundary lines and emit the illumination pattern to a side of the vehicle, and the projection lens focuses more of the light emitted from the light source passing outwardly from the optical axis of the projection lens.
