  • Patent number: 11906123
    Abstract: A light source module is switchable between a high beam and a low beam, and is mounted on a vehicle. A first light source is arranged such that its output light is irradiated to a low-beam region by a first optical system. A second light source is arranged such that its output light is irradiated to a high-beam region by a second optical system. A lighting circuit supplies a driving current to the first light source in response to a turn-on instruction for either the high beam or the low beam. Furthermore, the lighting circuit supplies the output current to the second light source in response to a turn-on instruction for the high beam.
