I have a set of lumenocks, with the little internal switch for shut off. Ive already broke one nock trying to shut it off because you have to use a knife point or something to stick inside and flip the switch. i was contemplating using a bit of Glo On or Gun Glow and putting a few drops on the inside of the nocks that came with my arrows, in the hollow part near the end. has anyone done this or something similar to make their own glow in the dark or lighted nocks?
