Abstract: A decorative light is disclosed. It includes a hollow base seat having a bulb seat on bottom portion for a bulb to fit in. The bulb is surrounded by a thermally insulated sheet which is spaced from the base seat and the bulb by a certain distance. A top end of the base seat is formed with a through hole in which a container is fitted. The container contains a liquid inside, which is dyed into a predetermined color and mixed with a plurality of polished plates. In use, the bulb radiates light and heat to the container to stir up the liquid, so that the polished plates are rolled to reflect the light and create a dynamic flickering effect.
