Night lights have become increasingly popular in recent years, both for practical and decorative purposes. They provide a soft, comforting light in the dark and help lull babies and children to sleep. Night lights can also be handy for late night trips to the bathroom or kitchen. Night lights come in a variety of forms. There are traditional night lights that plug into wall outlets and are often made with child-friendly designs featuring planets, animals or cartoon characters. There are also battery powered night lights that are great for camping or for when there is no outlet nearby. The newest night lights are often technological marvels. Smart night lights use motion sensors to detect movement and turn on only when needed. Connected night lights use the smartphone app to adjust the brightness or color. Some night lights even react to sound, like music, by changing the hue of the light display. Night lights are a great way to make a dark room more inviting and reassuring. Theyre a fun way to personalize the look of a space. And, of course, they provide the perfect amount of light for those middle-of-the-night trips to the loo.
