An example of a modern LED flashlight
Recently, LEDs have found their way into all kinds of applications, but one of the most important, especially for those who camp, hike or even drive to remote locations, is the LED flashlight. The LEDs used as a light source are highly unlikely to fail and produce much more light than traditional designs. Some of the newest LED flashlights can literally produce 10 times or more light output than incandescent lights using less energy, and thus providing longer battery life.
An advantage offered by some of these lights is the ability to signal with them. A flashlight based on the newest LED technology can be spotted from miles away. I have one from a well-known manufacturer of heavy duty flashlights that uses three AA batteries and produces more light than a 12V lantern does, while weighing much less. There are other manufacturers that produce similar lights, some of which have a press-on button on the rear of the flashlight. These are the best for signaling.
You will pay $30 or more for one of these, but that money may just save your life one day.
Even with the extended battery life provided by these new flashlights, it is still recommended that you keep plenty of spare batteries and even a backup flashlight with you on a trip.
