I shoot Gold Tip Kinetics and just got a 3-pack of nocturnal lighted knocks off of ebay for $19 delivered. Yesterday evening was the first time I've ever shot lighted nocks, I just swapped them in and shot at my 40 yd target, no change to point of impact. They worked perfect every time, they're a little bit of a pain to turn off but not hard with a knife tip once you get them figured out. I'm going to give them a try on whitetails this year. 99% of my shots are right at dark and I can see where these would make finding the arrow a lot easier. If nothing else they're just seriously cool to watch in flight and it makes seeing your impact a lot easier on the target. They were so neat that I went out and shined the 4 wheeler lights on my 40 yd target at 11pm last night & shot a bunch more in the dark just to watch them glow!
