A light source module 100 is switchable between a high beam and a low beam, and is mounted on a vehicle. A first light source 110 is arranged such that its output light is irradiated to a low-beam region 12 by a first optical system 4. A second light source 120 is arranged such that its output light is irradiated to a high-beam region 14 by a second optical system 6. A lighting circuit 130 supplies a driving current IOUT to the first light source 110 in response to a turn-on instruction for either the high beam or the low beam. Furthermore, the lighting circuit 130 supplies the output current IOUT to the second light source 120 in response to a turn-on instruction for the high beam.
