an illuminated ornament having an electronics assembly including a battery holder , a cap , a light emitting source and a control circuit is inserted through a hole axially into the ornament enclosure thereby locating the light source at a distance from the enclosure wall . the enclosure wall allow light to travel therethrough . a diffusing and reflecting cap which is preferably conical shaped converging towards a disk shaped end wall surrounds the light source and both allows light to travel therethrough and reflects light behind the light source to the enclosure wall . the battery holder is permanently attached to the assembly cap and the electronics assembly is removable from the enclosure in one piece . the assembly cap closes the hole . the differential pressure between the inside and outside of the enclosure is relieved preventing air and water entry through the assembly cap to enclosure interface .
