Abstract: A selectively illuminated jar which truly exemplifies the happy mood associated with sunshine by operation of an illumination system within the jar. A clear plastic jar is connected at its top with screw-on cap. An illumination system located at the top of the jar includes a substantially semicircular lens which simulates a sun-like surface. Within the lens is a light bulb, a battery and a switch which selectively electrically connects the battery with the light bulb as the cap is screwed on with respect to the jar. Optionally, the bottom of the jar may have a reflective surface to increment the lighting effect of the jar. Further, the bottom portion of the jar may include a cup upon which selected writing may be placed, such as "Sunshine in a Jar". Alternatively, the writing may be placed directly upon the jar itself.
