A random idea, I love wearing my lights on the outside, but as you can imagine, there’s a real risk of the light falling off (it happened to me once, but luckily I had secured it with a second protection).
So, I found a second use for a quick-release ring, originally designed for keychains, for the light!
That way, if the light accidentally comes loose and falls, it stays hanging 😉
(You will probably find cheap rings around your home, this one is taken from the Covalent Keychain, a recently successfully Kickstarter project now over)
