A dimpled golf ball for use after dark. The ball is made of translucent plastic and contains in a diametrical hole therein a chemiluminescent light stick which when activated renders the ball when used in the dark plainly visible in the air and on the ground. In a preferred form, the ball is made to comply with the rules of the United States Golf Association so that it may also be used for competitive daytime play. In a modified form the, resilience of the ball may be substantially diminished so that it will travel a much less distance than the preferred ball when hit with the same club.
