Some of the more common uses for a red light emitting diode (LED) flashlight are stargazing, hunting with a night vision scope, or military operations. This is because the red light that is emitted from this flashlight is more visible at nighttime than other colors of flashlight bulbs. It may still be used during the day for signaling, reading maps, and other tasks.

Members of the military often use a red LED flashlight when conducting night operations. This is because the red light helps them navigate in remote areas but cannot usually be seen from a great distance. As a result, service members can complete their mission while simultaneously reducing their chances of being spotted by the enemy.

Another group of people who often use a red LED flashlight are hunters, especially those who do so at night. The red flashlight bulb produces a light that provides better nighttime vision but does not usually scare away game. When used in conjunction with a rifle scope, this tactical flashlight greatly increases a hunter's chance of success when hunting both small and large game.

People sometimes use a red LED flashlight for stargazing. This is because looking for constellations should be done in complete darkness whenever possible, yet some light is needed in order to reach an optimum viewing spot. Using this red flashlight can help people get into position safely without creating light pollution that would reduce the number of visible stars.

A red LED flashlight does not have to be used at nighttime. One that has a cone-shaped head is often used to park cars at sporting events. It may also be used by emergency workers to direct traffic whenever there has been an automobile accident, whether at night or during the day. This is done by moving the flashlight back and forth in the direction cars need to travel.

One of the advantages of an LED flashlight is that the bulbs tend to last longer than those of halogen flashlights. The light from one of these flashlights tends to be somewhat brighter than the light from a traditional flashlight, but is not normally a strain to the eyes. There are many colors available, and some of the more common ones are red, blue, and green. It can be helpful to keep one of these flashlights on hand because they are good for a number of tasks, no matter what time of day they are used.

@browncoat - Actually, the best use I've ever seen of one was in a fun house a friend of mine set up for Halloween.

He managed to find a recording of a heart beat and put it in a room that was kept dark except for a super bright LED flashlight he hid underneath the floorboards. He set it on red and made sure it was flashing.

The light only leaked out a little bit, but when he managed to set it up so that the red flashes coincided with the loud beating of the heart it was really effective, as though the house itself was alive.

A lot of people told him that was their favorite part, even though it was really easy to do (although that was helped by the fact that he happened to have a loose floorboard and some gaps for the light to come through).

I really like using red LED flashlights in my Halloween display every year. Since they are LED they last for a long time and don't use up much battery power. And, of course, red is the best kind of light when you are going for a scary look.

One year I put a red flashlight behind a black cutout of some eyes and put it on a slow blink, which seemed to startle people.

And sometimes I put them into pumpkins, although white or blue lights will work just as well for those.

You can get really creative with red LED lights.

Red colored light is really good to use whenever you need your night vision to be sharp.

When you use a white or blue light, like a normal flashlight, your eyes adjust to it by narrowing your pupils. This means that you can't see in the dark very well.

But, if you use a red light your eyes won't adjust to it like that and if you turn it off you should still be able to still quite well in dim light.

I keep a red light near my bed so that if I wake up in the night it won't blind me when I turn it on. It also means I don't have to turn on every light in the house in order to see where I'm going, as light from the windows is usually enough when my eyes are adjusted.

It's just one of those little things that makes life a bit more comfortable.
