Night lights are devices that emit light to help with night vision. They are often used in homes to ensure safety and security. Night lights provide light when you need it in the dark. They are especially helpful when you cant find your way around your house or in unfamiliar places. In a dark environment, you can instantly see your surroundings and determine which way to head. Night lights also allow you to move around more easily in the dark. Night lights can also help to reduce nighttime fears by making shadows and strange noises less frightening. For children, it takes some of the fear out of going to bed, making it easier to relax and go to sleep. Some night lights also come with an adjustable timer that turns the light off or on at a specific time. But night lights arent just for safety and security. They can also add atmosphere to a room. A night light with a soft, comforting glow can create a soothing atmosphere in any room. Softer night lights can also be used to light up a hallway or bathroom so that its not pitch black when you enter at night. In short, night lights provide practical safety and security benefits and can also add an element of comfort and style to any room.
