Night lights are a staple of many homes. Set up in childrens bedrooms or along hallways, they provide a comforting source of light in the dark. But did you ever wonder why they are so popular or why they exist in the first place? The earliest night lights were mechanical lanterns used on ships or buoys. They were designed to provide a constant light source through the night to help guide ships to their destination. This concept was introduced into homes in the 1920s when engineers started to use electricity to power night lights. Not only are night lights practical, but they provide a sense of comfort and security for children and adults alike. Having a light source nearby reassures many people that the night is less intimidating. The popularity of night lights has grown especially in recent years as people look for ways to reduce their electricity costs. LED night lights are an energy-efficient solution for lighting any room.
