Lumenok
Lumenok® is made by the Burt Coyote Company®. The Vice President of the company came up with the idea during a hunting trip in 1998 after it took entirely too long to find his arrow after missing a buck. Like any new idea it was a journey of trial and error. They shot target with the nocks and hunted with them as well, continually tweaking the design. Finally, after 17 prototypes and four years of experimentation they filed a patent in 2002 and began production of the Lumenok®.
