Night lights are a form of lighting that brighten up the night's darkness to make it a little less intimidating. They help children to feel safer at night; provide security outside the home, and even make outdoor ambiance in city streets a little more pleasant. Put simply, they're the lights that make the night a little less dark. Night lights come in a variety of shapes and forms. Some of the most popular ones are the energy-efficient LED lights, which come in a variety of colors and designs. Night lights can be portable, wall-mounted, or installed in the ceiling. Some can also serve as nightlights for a whole room, with a timer setting that turns them off when a certain amount of time has passed. Although they are mostly designed for children, adults can also benefit from night lights. They can be a great way to light pathways for getting around the house in the dark, as well as to locate certain items or amenities such as a light switch or bathroom. Night lights can also make it easier and safer to get up in the middle of the night without having to turn on bright light, reducing the chance of waking others sleeping in the same house. In short, night lights can be an effective way to ease the transition from day to night, and make the night time a little less scary and a little more relaxing.
