Flashlights with beacon mode
Lighthouse
— the mode of infrequent flashes with a repeating amplitude, most often at a relatively low brightness (with some exceptions to the rule). In some models of torches, you can even find more than one version of the beacon. The mode is designed to detect and observe the user at a distance; at the same time, the beacon not only consumes battery power more effectively than a constant light of the same brightness, but is also better visible from afar. We also note that in headlamps, a flicker mode performs a similar function.Show
