TenPointAlpha-Brite Lighted Crossbow Nock, Red - Pack of 3 - For Use with Most TenPoint, Wicked Ridge & Horton Innovations Crossbows (Does Not Include Nitro 505)

The light sticks arrived basically dead on arrival, see the images. After a quick chat with customer service, they are sending replacement light sticks. I will buy from them again.Installation is a little quirky, it helps to have a vice of sorts that can hold the arrows without marring them. I used vise-grips, but they scratched the anodize coating. Rather than using epoxy, I used Bob Smith Industries extra-thick cyanoacrylate glue.

Worked great

All good, but they could make it a bit less sensitive, requiring a bur firmer push to activate. It turns on too easily, when you carry, move around, store, quiver the bolts etc. With the crossbow’s velocity pushing the arrow to fly, there is no risk that the light won’t be activated. But they made it so fragile that if you look at your arrow hard enough, the nock will light up.

Very good product. Used this entire season and was easily recovered after use. Lost bolts last year without lumiknocks. Bolts this year running +$25 ea. It was nice to find them the 2 times I needed them. Could say they paid for themselves. One quality note. Of the three knocks only 2 worked. Not worth the hassle to return.

I really like how easy it was to install. A little know how is needed.

Installation is easy, and they work properly but don’t use them in practice, if you have a pass through the nock will come off in the target as with all alpha nocks I have used

After converting the bolts I shot them to see how they worked without the lights installed.It seemed as they were more accurate and I found less wear on the string compared to theOmni Nocks. With the lights installed they worked very well. The lights lit at the shot and wereeasily turned off by pulling the nock off the bolt and removing the light and pull the bulb until itturned off.My biggest concern is I thought that the nocks could be pulled out by brush or whatever too easily.That concern was confirmed on the first hunt of the season. After I returned to my vehicle I found anock lit It was an easy fix to just turn the light off. On the same afternoon I returned to the vehicleand found a nock was missing from one of the bolts. It had pulled out of the receiver somewhere inthe woods.I called TenPoint and spoke to a customer service representative. She was very helpful as they alwaysare and suggested I could try to wrap some scotch tape around the base of the nock to tighten them up.I tried it but it doesn't help.In conclusion, I would buy the Alpha Nock receivers and nocks again but not the lighted nock kit. I wouldglue the Alpha nocks into the receivers to get the accuracy and reduced string wear. You can't glue themtogether if you want lighted nocks. I don't know if I can get a refund for the lighted nock kit after I usedthe receivers and have a missing nock and light. It is for these reasons I give the lighted nock kit two stars.

These are great. They basically light as you pull back the arrow. Easy to install, andceasy enough to turn back iff by pulling then back off the noxk.

Best ever
