Take your game of golf to the evening skies by using these novelty light up golf balls! Available in four colors, this high-tech golf ball will provide up to a total of 36 hours of illuminated fun and excitement. Once the ball is activated, the two high powered LED lights will illuminate the ball for 8-10 minutes until the automatic shutoff turns off the lights to preserve battery life. After shutoff, all it takes is another strike of the ball to re-energize the circuitry for another 8-10 minutes. With customization options, it's a great giveaway for corporate sponsorship events, mini golf centers, pro shops and much more!
