A nightlight is a small, usually electrical lamp that provides minimal illumination in a dark space. It's typically placed on a table or floor to provide soft and soothing light during the nighttime hours, helping people navigate their way around a room without turning on bright lights which can disrupt sleep patterns. Nightlights are often used by children who may be afraid of the dark, as well as adults who need a little extra illumination while getting up in the middle of the night or walking through a dimly lit hallway.
