Abstract: An apparatus for illuminating the interior of a balloon includes a cylindrical plug with an integrally-formed radially extending integral flange insertable within the balloon neck. A light element is affixed to the plug and disposed within the neck. A battery is electrically connected to the light element and is typically mounted next to the light element, or includes the light element in a single assembly. Switching is provided to turn the lighting element on and off which, in the preferred embodiment is effected by inflating the balloon with the apparatus inserted into the balloon neck. The light element may be affixed to the head of the apparatus by magnetic means, by means of a screw-on cap, or by other well-known techniques.

Abstract: A re-usable, self-illuminating sign includes a translucent plastic photoluminescent display panel, disposed within a display body, the display panel formed by distributing a photoluminescent powder uniformly throughout the plastic. A chemiluminescent light stick serves as a light source for the sign, which is in the form of a cylinder with a triangular cross section. When the light stick is exhausted, it may be removed from the display body and replaced by a new light stick. The photoluminescent display panel receives the light from the light stick, and retransmits the light uniformly throughout the display panel. A mask disposed in front of the display panel contains cutouts providing the the text and/or graphics of the sign.
