You can normally buy LED lights for GLOW golf on Monday nights at the Olathe course between 5:30 and 6:00, but I have sold out and won't have any again until next fall when we start GLOW golf league up again. You can also buy them at Waterworks Park on Thursday evenings between 5:30 and 6:00, but Ted, who sells them might also be out currently. We both sold them for $2. You can go to Wal-Fart and get them though. They are in the fishing tackle area, and go for around $2.50. Hope that helps.
