Claim:
An apparatus for illuminating an inflatable structure from within, comprising: a housing having formed therein a region for accepting a power supply and a region for accepting a control circuit; a control circuit disposed in said region for accepting a control circuit, said control circuit including circuitry for providing a time-modulated voltage to a light source electrically connected thereto; a cylindrical spacer having an external diameter, secured at a first axial end thereof to said housing, configured to receive a portion of an inflatable structure and provide a surface against which that portion of the inflatable structure may be secured; a shoulder flange having a region whose diameter is greater than the external diameter of said cylindrical spacer, secured to said cylindrical housing at a second axial end opposite said first axial end, configured to permit the placement of a portion of an inflatable structure thereover, but to resist removal of that portion of the inflatable structure; an elongated cylindrical body secured at a first axial end thereof to said shoulder flange and extending axially away from said housing; a polychromatic light source secured at a second axial end of said elongated cylindrical body opposite said first axial end; and electrical interconnections connecting said polychromatic light source and said control circuit.
