well gold tip has changed its nocks made them longer. This is what i do just buy a dozen nocks from ebay or where you can in fl red or fl green. then buy a dozen thill bobber lights from wally world or directly from thill 2/pack i belive. now take super glue and coat around the outside of the pull out bulb section and push the light all the way in the nock , let dry, to turn on pull or push battery tube at the bottom of the nock, i use mine during hog hunting and just turn them on when it dark it does't spook the game...
