Word from LFGSS ( http://www.lfgss.com/ ) is that this is useless.

It's too low powered (40 lumens), and no-one suffers stolen lights (they're all removable in an instant). Equally powerful lights are incredibly small and can be fitted and removed in literally a few seconds.

None of us believe we are experiencing the problem that this solves, none of us get lights stolen.

What we do suffer is stolen saddles (detached from seat posts), and stolen hubs (bolt-cut the spokes of and steal the hubs).

But for those problems, this startup ( http://atomic22.co.uk/ ) are almost there at bringing to market a total bike security product in which every bolt on the bike is part of the same security system.
