Not everyone of us are privileged enough to live in homes or apartments that have decent lighting as we walk up to them, let alone those automatic lights which come with a sensor to detect whether there is someone at the doorstep, turning on its spotlight so that you will have an easy time looking for your keys in your handbag. With the Nite Glowring, things could be different for the rest of us ordinary plebeians.

The manufacturers of our Glowrings, who produce military equipment and other need-to-see-at-night items, have taken this everyday nugget of basic science and made it their business. A Glowring is small enough and tough enough to attach to anything you might need to use in the dark, a bunch of keys being the most obvious. But because they can glow for up to a decade, you can leave them hanging off things that only come out once in a while like fishing gear and camping equipment. It does have to be pretty dark to see the glow, but that’s the point.

Sounds like £9.95 well spent if you tend to live the life of a night owl, retiring for the ‘night’ when the garbage trucks and street sweepers are starting to make their rounds.
