A nightlight is a small, low-powered light designed to provide illumination during the night. It is often used in bedrooms, hallways, or bathrooms to help people navigate in the dark without turning on bright overhead lights. Nightlights can be plugged into electrical outlets or powered by batteries, and they come in various designs, colors, and brightness levels. Many nightlights use LED technology, which makes them energy-efficient and long-lasting. Some models feature automatic sensors that turn the light on at dusk and off at dawn, while others may include fun designs, such as cartoon characters or animals, making them appealing for children.
