Night lights are used for a variety of purposes. Since ancient times people have placed lights in their homes that they would light in the evening for security, lighting, and comfort. In the modern era, night lights can serve many different functions. For children, night lights provide safety and comfort. They are often used to keep a child from feeling scared in the dark or as a way to help them sleep in the peaceful blue or green glow. Many night lights also have a timer so they can be set to turn off after a certain amount of time. Although night lights are mainly used for children, parents and adults can also benefit from them. A night light can be used to provide ambient light while reading at night or navigating a darkened hallway. This can help prevent slips or falls and make sure everyone is safe. Some night lights are also equipped with motion sensors so that they turn on only when needed. Along with increased safety and comfort, night lights can also provide artistic decorations. Many people enjoy looking at night lights that come in a variety of designs and colors, adding some character to a room. Night lights are a great addition to any home, being both functional and attractive. Whether theyre used for children, parents, or decoration, night lights can provide a sense of security and comfort.
