Night lights, also known as night lighting, are lights that are used at night to provide illumination. Most night lights use low- or no-wattage bulbs to provide soft illumination without sacrificing energy efficiency. They are typically used for safety purposes, such as lighting hallways or staircases in residential homes, as well as providing visibility outdoors. Night lights are available in a variety of styles, from plug-in wall fixtures to battery-powered models to light switches with built-in timers. Many modern night lights feature additional features such as motion-sensing, allowing the lights to turn on automatically when motion is detected. This can save energy by turning off after a certain amount of time if there is no movement. Additionally, some night lights include features such as adjustable dimmers for the light intensity, as well as built-in alarms to alert users when the lights are activated. Night lights are popular for a variety of reasons. They can provide a sense of security for children who may feel scared at night, as well as helping adults feel more comfortable while going about their evening activities. Additionally, night lights can help provide visibility for navigating stairs or hallways, which can be especially important for elderly people who may have difficulty seeing in the dark. Night lights provide a welcome source of light in an often dark and unfamiliar environment. They can provide an extra layer of security, help seniors stay safe, and even improve the visual appeal of a home.
