ABSTRACT:
A vehicular headlamp is provided. The vehicular headlamp includes a headlamp which emits light; an indication lamp comprising semiconductor light-emitting elements as light sources; and an electric circuit which supplies a current to the indication lamp. The indication lamp is divided into at least two light source sections comprising respective sets of light sources, and at least one of the light source sections is disposed in a high-temperature region whose temperature is made higher than in a remainder of the light source sections while the headlamp unit is lit. The electric circuit controls the light source sections individually so that a current supplied to the light source section disposed in the high-temperature region is made smaller than a current supplied to the remainder of the light source sections.
