This is a combination of conductive pompom and tilt sensor. The advantage is that the pompom has much bigger and softer surface than metal bead, which helps for it to touch the tilt detecting conductive fabric. Also it gives a certain look, that may be desired for some projects.
Here is the schematic of this simple 3LED circuit. I used 3V button battery pouch to hold my battery. You can also use double AA batteries.
And here is the video of how it works..
It is very sensitive and smooth.

It can produce about 900 lumens and produce a beam of 240 feet long by just a single LED and reflector only. The special waterproof material can prevent the invasion of liquid.
