The party never has to end again with these LED bocce balls. All of the balls, even the target ball, is lit with a built-in LED lamp, allowing you to see it in the twilight hours. Get a night league going, or entertain the relatives for days on end. Be a roaming bocce champ, carrying the set from town to town in the convenient wooden crate style case. Powered by button cell batteries. All you need is a flashlight/pen to keep the score.
