If something along these lines gets the initiative and gets approved, it would be great for night golf. I would love to not have to charge a disc before every throw or tape LEDs to them. I do see it as possibly causing a big shift in the way that "day" discs are produced though, especially if discs would be allowed to include metal within them as long as they were "intended for night golf."
Anyways, ideas? thoughts?
