Daddus don't shoot a crossbow just a compound but have used lighted nocks for about 10 years I started with the Stingers (worst I ever used)
then went to the B.C. luminocks then tried a bunch of others till I settled on the Nockturnals. They are not perfect but the best & brightest I have used so far except for the fact you can not replace the batteries I am starting to work on making my own now & will see how they work out does not seem hard to do & savings is $3-$5 depending on which ones you buy
