Ever needed just a bit of light? Enough to see the door lock or read co-ordinates in rough terrain. This keylight might suit your needs. Small enough to be put on the zip pull of a jacket, bright enough to see close items by. As well as the attached D clip in the photos, this keylight also features two methods of operation, either just squeeze for momentary light or flick the switch to turn on. Takes 2 x CR2016 batteries which are included.
