A low-beam-color-temperature-variable headlight unit (10) includes a case (21), a condenser lens (24), a high-color-temperature light emitting diode (22), a low-color-temperature light emitting diode (23), and a low-beam-color-temperature control unit (7). The high-color-temperature light emitting diode emits high-color-temperature light. The high-color-temperature light emitting diode provides illumination of a first illuminated area (31). The low-color-temperature light emitting diode provides illumination of a second illuminated area (32) that overlaps the first illuminated area (31) at least partly. The low-color-temperature light emitting diode emits low-color-temperature light having a lower color temperature than the high-color-temperature light. The low-beam-color-temperature control unit is capable of adjusting the color temperature of the low beam by adjusting the quantity of light emitted from the high-color-temperature light emitting diode and the quantity of light emitted from the low-color-temperature light emitting diode.
