Guess I would have to rebalance for the added weight.

"Weighing in at only 18.5 grains, the Lazer Eye nock is only 8 grains heavier than the standard Carbon Express nock..."

8 grains is the stated increase over carbon (arrow) nocks. I don't know what kite nocks tend to weigh (are they carbon, or just plastic?), but:
8 grains = 0.51839128 grams, per Google.
18.5 grains (total nock weight) = 1.19877984 grams

I think you're okay with an extra paperclip's worth of weight on the kite. If not, I'd be more worried about all the running around you're doing in the dark to keep the kite up.  ;)

many arrow nocks utilize metal inserts.  so the 8 grains added may be referring to a nock that weighs more than your standard plastic wingtip.

Fair enough, but a total weight of 18.5 grains per nock isn't going to pull a kite out of the sky.

The Lazer Eye is activated upon release of the arrow, when the bow string compresses forward upon the arrow

I suppose a good tip stab would get them shining?

I think any compression on them will light them up. Pulling back on the nock is supposed to turn it off. So, they'd be always on for a kite, as long as the LE is tensioned, right?

or in my case a good lawn dart

I'm better at those too ,,, we need something designed to go on the nose   :D

Yeah that appeared to be the process, looks like they have a rubber plug that sticks in the spar and operates a switch when the nock is compressed toward it.

That was lad (http://www.gwtwforum.com/index.php?action=profile;u=740), in the thread, Ideal, tiny LED for SLKs? (http://www.gwtwforum.com/index.php?topic=6855.msg60788#msg60788).  Interest dropped off a bit when it became apparent that the batteries were not replaceable.  So they were basically disposable.  Not sure if the nocks have replaceable batteries or not.

The Lumenok consists of the nock, battery pack and two plastic sleeves that encase the battery and put pressure on the shaft to hold the assembly in place. The flat of the nock that contacts the back of the shaft contains two metallic loops that are used to complete the electrical circuit and turn on the LED when both loops contact the arrow shaft. Before the shot the nock must be pulled slightly out of the shaft so that the contacts are not touching the shaft. As the arrow is shot, the force pushes the nock tight against the shaft and engages the connection loops. The Lumenok is the only nock in the test group that is not an indexed nock. While a minor detail, I generally only use indexed nocks so as to not have to constantly look at the fletchings to line nocks up. This test version weighs 30.6 grains and will last up to 40 hours while lit; replacement batteries are available for ~$5.

I think this nock cost @$9. Yes, not all nocks have replaceable batteries.
Based on the speed of current bows, these should survive nose plants.

Can buy a lot of LEDs + cr2032 batteries + cr2032 housing for $9 on ebay then just need some wire.  Tried something like this before, worked best when the lights where taped on to the standoffs pointing up towards the sail.  Can get some blinking LED and wire them in parallel so some stay on while others blink.

There are a bunch of options on Amazon.

Been a lot of interest in lighted kites lately, my brother in law sent me this link to a "Cool Kite" he found, technically not a kite but it's not about that. Watch the second "How To" video for the simplest lighting technique I've seen. Oh and ignore the balloons too.

In short duct tape an LED to a 3 volt button battery, I like simple   :)   8)
