A night light is a small, low-intensity light designed to provide illumination during the night. It helps create a calming environment, making it easier for individuals, especially children, to feel safe and comfortable in the dark. Night lights can be plugged into electrical outlets or powered by batteries, and they often come in various designs and colors. Using a night light can aid in sleep by reducing anxiety associated with darkness. It can also help with nighttime activities, such as using the bathroom, without the need for bright overhead lights. Many night lights are adjustable, allowing users to control brightness levels to suit their preferences.
