Night lights, also known as night-lights, fill a necessary role in everyday life at home and at work, and throughout the world. They provide a sense of security and comfort in the dark. Night lights come in a variety of shapes, sizes, styles, and colors. Some may offer a gentle glow, while others can provide a full landscape of vibrant lighting. Modern night lights are equipped with energy-saving technology, meaning they can be left on for long periods of time without drawing a large amount of energy. Not only are night lights handy for areas of a home or office that may receive little or no light from exterior sources, they can also help relieve stress for those who are afraid of the dark or have difficulty sleeping. Night lights can provide a sense of security that will help those who fear the darkness or may need help getting to rest. Night lights offer a wide range of practical uses, such as providing a soft light to help make it easier to find the restroom after the lights go out in the middle of the night, as a subtle addition to the bedroom to soothe a child, or for use as an emergency light in case of a power outage. Night lights take on many forms but all offer a useful way to help make dark spaces a little brighter and more comfortable. They are versatile, energy efficient, and provide much-needed security and comfort in the dark.
