There's simply nothing worse than a power cut to really put a dampener on things. Suddenly, finding your way around becomes a challenge, never mind locating those must-have items. Like keys. Keys. Why is it always keys? And when you tell your dearly beloved that you've lost them (even in the daylight) what do you get back? 'Where did you have them last?' That surely ranks among the most unhelpful responses known to man. Now there's no need for that question. Nor the predictable reply. Not with the invention of the Nite Glowring, that is. Now your keys, when attached to this glowing keyring, will be visible from 30 feet, even in complete darkness. Don't just restrict yourself to keys, either. Attach the handy ring to bags, torches, camping gear, mobile phones and more for instant visibility.

The secret ingredient is a little magic called Gaseous Tritium Light Source - or GTLS for short. It'll keep on glowing for a whole ten years, continuously burning away without the need for batteries inside a durable polycarbonate shell, and thereby keeping your most prized possessions in sight right the way through until 2018. Now there's a thought.
