A throw ball made of light, translucent material contains an electric bulb or light emitting diode powered by a small battery. The ball is made of two separable, similar half-sections having symmetrical axial tubular cavities housing the electrical assembly. An illuminating switch is activated when the two half-sections are brought together and aligned to a discrete operating position, and de-activated when the two half-sections are rotated away from said operating position.
