Abstract
A game ball has a hollow spherical shell with at least a portion thereof that is translucent. A plurality of dimples are disposed on the outer surface of the hollow shell. At least some of the dimples comprise double concave negative lenses with a convex portion generally concentric with an outer concave surface of the double concave negative lenses. An impact triggering mechanism, a power source, and a light source are contained within a bulb that is contained within an open inner volume of the hollow shell. Upon impact of the game ball with an outside body, the impact triggering mechanism sends power from the power source to energize the light source. Light is emitted and refracted through the lenses whereby the game ball tends to glow and attention is attracted to the game ball. A volume of liquid is contained within the open inner volume of the hollow shell for dampening energy and protecting the bulb.
