An alternating current-direct current daytime running lamp variable-voltage control device is composed of a first relay, a diode, a transformer, a second relay and the like. The alternating current-direct current daytime running lamp variable-voltage control device is characterized in that the common end of the first relay leads out an outgoing line, one end of a coil of the first relay is connected with the normally open end of the first relay and leads out an incoming line, the other end of the coil of the first relay, one end of a primary coil of the transformer, one end of a secondary coil of the transformer and one end of a coil of the second relay are arranged in parallel to lead out a negative pole line, the other end of the coil of the second relay is connected with the normally closed end of the second relay, the common end of the second relay leads out a power line, the normally open end of the second relay is connected with the other end of the primary coil of the transformer, the anode of the diode is connected with the other end of the secondary coil of the transformer, and the cathode of the diode is connected with the normally closed end of the first relay. The alternating current-direct current daytime running lamp variable-voltage control device has the advantages that the original lamplight has two purposes, the functions of original loads and a daytime running lamp can be directly controlled by means of an original switch, and resources are saved; meanwhile, an MOS tube and a control part which are needed for oscillation of an original transformer are omitted, and the economic effect is prominent.
