Night Lights, also known as lantern lights or night lamps, are objects with light sources installed or placed outside a building or dwelling to illuminate the nighttime environment. They have multiple purposes, including providing safety, signaling, and decoration. Night lights can be powered by electricity, solar, chemical, oil, and gas. Electric night lights are very common and use a variety of sources such as solar panels, wind power, and batteries. The solar type usually comes with a sensor that turns it on at dusk. Wind power lights are usually a bit more expensive but eco-friendly. Chemical night lights, oil lights, and gas lanterns are also becoming increasingly popular, offering efficient light, portability, and eco-friendly options. They can also be useful in terms of protection and signaling, since they can provide a visible signal of someones presence or possessions inside a property. They are also used to light up pathways so that people dont trip or fall in the dark. On a more aesthetic level, night lights can be used for decoration. During the holiday season, for example, they are often seen decorating homes and gardens. In conclusion, night lights can serve many purposes. They can ensure safety by providing visibility, decorate and beautify properties, and even signal the presence of an individual or property. They come in various forms, from electricity to oil or gas, and can be adapted for use in almost any environment.
