Night lights have become a staple of many childhoods. These powerful sources of light, which are generally used as aChild safety aid, provide a comforting and calming feeling of safety and security. It may come as no surprise that the origins of night lights hearken back to the simple nightlight used in ancient days. In these primitive versions, a candle or oil lamp was left burning at night in a communal area of a house, such as a hallway or bedroom. This provided enough light to allow people to safely move around in the dark without risking any dangerous falls or stumbling. In the modern era, the advent of electric lighting has made nightlight designs a relatively simple matter. Nightlights are generally electric plugs that fit into regular wall sockets, or ornamental nightlights that are powered by a battery or even a USB port. They usually emit a warm, soft light that can be adjusted in both intensity and color, adding a cosy warmth to a child's bedroom. Night lights are not just toys for children; they are also a source of safety for adults. Even if a person is unable to completely darken their bedroom in order to get a good night's sleep, nightlights can provide a soft light, which is enough to make movement cautious and determine obstacles, yet not bright enough to disrupt a night's sleep. Night lights can also be placed in strategic spots outside a home, such as a stairwell, pathway, or other dark area. This can provide a source of illumination and prevent accidents. Night lights are not only practical, they are also decorative. They can add a whimsical touch to a child's bedroom or provide a neat design element to an adult's bedroom. The large variety and styles of night lights available make them an ideal accessory to fit any room and any style of home. In short, night lights are a great way to provide safety, security, and even a touch of charm to a home.
