Abstract: An illuminated game ball for use in playing a field game at night. The game ball includes an illumination case mounted within first and second shell halves and having batteries that are selectively connected to an LED for illuminating the game ball for nighttime play. A cap in the ball is rotated to one of three selective orientations to either illuminate the LED, extinguish the LED, or be removed to provide access to the battery compartments. Ideally the game ball is formed from translucent or transparent plastic that can be tinted with various colors.
