What is it?

A flashlight is a portable device that provides an electrically powered light source. The light source is usually a small LED or incandescent light bulb. They are support and protected by a case. The most common power source is a battery. These can either be disposable batteries, like lithium, alkaline, or button cells, or rechargeable batteries. The choice of battery determines various factors, including the shape, run time, weight, and size of the flashlight. Flashlights that are used for extended periods of time tend to run on rechargeable batteries. Another type of flashlight runs by using a winding crank and spring which is connected to a dynamo (a small electrical generator). These flashlights are useful during an emergency, when batteries or other forms of power may not be available.


Flashlights are incredibly useful in emergency situations, which is why they are included in almost all emergency kits. While they are generally used for small tasks, such as looking for something in dark closets or during a brief power outage, but there are situations where a flashlight can help save your life. During earthquakes, for example, the first thing to go is usually the power. If you are stuck in your basement, it can be incredibly dangerous to get around if you can’t see. A flashlight will also allow you to find important items to take with you before you evacuate. You should also always have a flashlight with you when you go hiking or camping. During the night, it can be very difficult to see clearly, which could cause you to potentially fall or hurt yourself. Having a flashlight (or two) will help you see even during the darkest of nights. Lastly, flashlights are very handy during roadside emergencies. If you get a flat tire or your engine breaks down on the side of the highway at night, it can be very difficult to see what you are doing. Having a flashlight with you will allow you to see where the problem is and hopefully fix it, and get back on the road again.

Because they are usually small, inexpensive, and easy to buy, most people do not take proper care of their flashlights. Whether you have a $100 or $5 flashlight, there are several steps you should take to ensure it stays in good condition. The last thing you want is to encounter a situation where you need a flashlight but discover the one you have isn’t working. Store your flashlight in a cool, dry location that is easy to reach. You should also replace the batteries in your flashlight every few months, even if you haven’t used it. You should also store your flashlight in a location with extra batteries. That way, if you try to use it but discover the batteries are dead, you have some nearby you can use. Do not leave your flashlight stored in an area where it will be exposed to high temperatures or direct sunlight, because this could cause battery leakage, which could be extremely dangerous.
