Abstract
A vehicular headlight () includes a first light source unit (), a second light source unit (), a temperature sensor (), and a control unit (). When the temperature derating is performed on the first light source unit () based on the temperature in a state where the light distribution pattern () of a low-beam is formed, the control unit () controls the power to be supplied to each of a plurality of light-emitting elements () so that the light amount of at least a part of the first light with which at least a region () of a first light distribution pattern () is irradiated decreases as compared with that before the temperature derating.
