The size and cost of a lighting device can be reduced by monitoring a plurality of input states and changing an output using a common coil or common switch element. A powder converter receives a plurality of DC powers, which are received in different modes, have a common ground and substantially the same potential, and operates a plurality of loads. The power converter operates the loads according to input states of the plurality of DC powers and supplies the plurality of loads with power via at least a common switch element or a common coil. A first DC power is power supplied via a switch for turning on a passing beam of a vehicle. A second DC power is power supplied in tandem with an ignition of the vehicle. A first load is a vehicle headlight. A second load is a day time running light (DTRL) of the vehicle.
