I love these things, use them when I film all the time. Batteries died on a few so I took them apart. They are very simple to build, .15 cent led and a 3 dollar, 3 volt battery, a little wire and drill a small hole and thats about it. Ordered the parts from mouser for a little over $3 a nock. If anyone is interest I can dig out my packing slip and give you the numbers. The best thing I liked, was I was able to build them with my nocks. The factory fit a little loss needed to always shim them. Granted you are only saving a 9 bucks on retail and about 5 if you find them on sale, But I do beleive with the super bright red LED I got, mine are a little brighter. Let me know just thought I would pass it along.

Yep I'd like the Bill of materials if you can find it. Just PM me if you can find it. Thanks
