Our 9-pack of LED Green Golf Cup Rings are an alternative to the traditional glow-in-the-dark cup rings and an easy way to quickly identify the cup. Each LED cup ring has 3 modes of operation: steady, fast/slow flash. They are battery-operated and will have approximately 9 hours of usage time.  Just insert into the cup either as a "bracelet" or in an "open" position and start the flash. Batteries included & installed. Just perfect for 9 holes. Our LED light-up putting cup rings are sold 9 to pack. Please order in increments of 1 pack.
