DISCO FLASHING LED Electronic Golf Balls 2-pack ~ Lights up red green blue purple
Looks, feels, and plays just like a regular golf ball. However, this ball will light up after being struck. The LED light inside will shine for 5-8 minutes. This makes finding your ball very easy at night or twilight. The battery inside will last about 40 hours total, meaning you can strike the ball about 300 times.
