A balloon illuminator that can emit either a flashing or constant light depending on the polarity of the battery used to power the device. The device can be modified to cycle through a series of colors. The balloon illuminator is comprised of a lens, light emitting diode, a battery, and means to switch the balloon illuminator from flashing to constant light mode depending on the polarity of the battery and a housing lined with electricity conducting material. Once fully assembled, with each component contained in the housing, the electrical circuit formed by housing and components is closed and the balloon illuminator emits light. The balloon illuminator also works without a lens, though in the preferred embodiment, the lens is used to disperse the light more fully in the interior of the balloon. A balloon illuminator that uses a multi color light emitting diode can cycle through a series of colors once the illuminator is fully assembled and the electrical circuit completed. The balloon illuminator is impervious to liquid and is compatible with liquid sealants used to coat the inner lining of latex balloons to prevent leakage of gas.
