Night Lights Night lights are small lamps or lighting fixtures that are plugged into wall outlets and used to illuminate dark rooms. They are very popular with children and adults alike because they provide a comforting sense of security and familiarity in the dark. They are useful for adults who get up in the middle of the night to check on sleeping children. They are also perfect to light a dark hallway or closet. Night lights come in a variety of shapes and sizes. Some are made of plastic, some of ceramic, and some of glass. They can be as simple as a plain white light or as intricate as an animated nightlight with different colors and characters. Many shapes and sizes, as well as colors, illuminate a room or hallway with a soft glow. Some have a switch to manually turn the night light off and on, while others are operated automatically by a light sensor. Night lights are also very helpful for maintaining night vision. If youre trying to get used to a dark room or hallway, a night light will help you adjust your vision gradually without disrupting your sleeping cycle. Additionally, some night lights can be used in conjunction with light therapy to help with seasonal affective disorder (SAD). Just as there are many uses for a night light, there are many types of night lights to choose from. Most hardware stores carry different types and styles, as does any online retailer. Whether you are buying night lights for your own home, a childs bedroom, or as a gift, you are sure to find something perfect for any occasion.
