Abstract: An illuminatable golf ball includes an outer translucent shell and a sealed inner core portion surrounded by the outer shell. The ball includes a self-contained lighting device formed and contained at least in part within the inner core portion. The lighting device includes an energy source, a pair of lighting elements, and connectors extending between the energy source and the lighting elements defining an electrical circuit. The lighting device includes a switch for energizing and deenergizing the lighting device. The switch can include a plunger insertable into the ball through an opening in the outer shell and through a bore in the inner core portion. The plunger is configured to change the state of the electrical circuit when it is inserted into and removed from the bore to energize and deenergize the lighting elements. The switch can also be timer actuated and of the force actuatable type.

Abstract: An illuminated balloon includes a substantially gas-impermeable membrane capable of pressurized gas storage and a self-contained illuminating member fully positioned within the balloon. The membrane defines a gas storage region having an inner surface and an outer surface and a neck portion. The neck portion includes an opening therein for introducing a gas to inflate the balloon. The illuminating member is self-contained and includes an illuminating element and a power source electrically connected thereto. The illuminating member, including the power source, is completely within the gas storage region. The illuminating member can include a light emitting diode (LED) and circuitry to provide pulsating power to the LED.
