A massively useful idea, the ClipLit from Nite Ize allows you to easily attach a bright, water resistant light to all manner of things.
The ClipLit is an LED, encased in a durable plastic housing attached to a rugged plastic carabiner clip, which turns on and off with a simple twist. Attached to a keyring for finding keyholes in the dark, or to a belt loop, zip-pull, rucksack, handbag, tent, etc, it's easily to hand when you need to shed a little light on the situation.
When attached to your clothing, it's an easy way to increase your visibility when walking at night.

Just a really sweet little glow bug, not usable as a torch but I clip mine to the dog collar when walking out in the dark, then I know where she is!
