A daytime running light variable-voltage control device is formed by a first relay, a diode, a transformer, a second relay and the like. The daytime running light variable-voltage control device is characterized in that an outgoing line is led out of the common end of the first relay, one end of a coil of the first relay is connected with a normally open end, an incoming line is led out of one end of the coil of the first relay, the other end of the coil of the first relay, one primary end and one secondary end of the transformer and one end of a coil of the second relay are connected in parallel, a negative electrode line is led out of the other end of the coil of the first relay, one primary end and one secondary end of the transformer and one end of the coil of the second relay, the other end of the coil of the second relay is connected with a normally closed end, a power line is led out of the common end of the second relay, the normally open end of the second relay is connected with the other primary end of the transformer, the positive electrode of the diode is connected with the other secondary end of the transformer, and the negative electrode of the diode is connected with the normally closed end of the first relay. The daytime running light variable-voltage control device has the advantages that an original daytime running light has two functions, functions of an original load and the daytime running light can be directly controlled with the help of an original switch, and resources are saved; meanwhile, a moss tube and a control part which are needed for vibration of an original transformer are omitted, and the economic effect is prominent.
