ABSTRACT:
A vehicle headlight device includes a lower beam unit for illuminating a lower beam, an upper beam/infrared ray switching unit for switching between illuminating an upper beam and an infrared ray, a low-beam abnormality detecting circuit for detecting an abnormality of the lower beam unit, a power-supply abnormality detecting circuit for detecting an abnormality of a power supply of the vehicle headlight, and a control circuit that inhibits the upper beam/infrared ray switching unit from illuminating the infrared ray when an abnormality is detected by either the low-beam abnormality detecting circuit or the power-supply abnormality detecting circuit.
