A decorative lighting string, which comprises a connector, a rectifier, an housing, a LED lamp and a PCB circuit board. The PCB circuit board is defined with an IC controlling circuit that is provided for controlling the flashing frequency and brightness of the LED lamp, and the LED lamp is electrically connected to the output end of the IC controlling circuit, and the LED lamp and the PCB circuit board are defined in the housing. The flashing effects of the LED lamp can be changeable by using different kinds of wafers, and the connector is connected with an ordinary decorative lighting string directly or connected with the direct current via the rectifier for supplying power. Therefore, this invention is secure and easily assembling.
