A LED flash bulb decorating light with features of able to achieve complicated light variation by employing simple circuit design, which comprises a power cord with a power plug, a series of single color, dual color or multiple color LED flash bulb forming in series or parallel circuit with the power cord. And a circuit control box comprises a low pass filter circuit and a power reset circuit and installed between the power plug of the power cord and the LED flash bulb, wherein the LED flash bulb at least comprises a LED chip and an IC driving element for driving the LED chip with DC power according to the setting time sequence to generate desired light variation. And the power reset circuit reset power supply at the repeated setting time interval to enable each LED flash bulb on the power cord to restart flash sequence to maintain the desired synchronous light variation.
