ABSTRACT:
Electric current supplied to light source rows of a vehicular lamp is controlled appropriately. The vehicular lamp includes: a plurality of semiconductor light emitting devices connected in parallel; a wire breakage detecting unit detecting wire breakage of each of the plurality of semiconductor light emitting devices; and an electric current supplying unit supplying a predetermined electric current to the plurality of semiconductor light emitting devices. The electric current supplying unit decreases the electric current to be supplied to the plurality of semiconductor light emitting devices when the wire breakage detecting unit detects wire breakage of at least one of the plurality of semiconductor light emitting devices.
