Night Lights, a feature of many homes the world over, is a source of comfort and security to many. They come in a wide variety of styles, shapes, colors, and sizes and may represent a number of things that lend themselves to a warm, inviting atmosphere. In many cultures, the use of a night light is a sign of hospitality. In Chinese culture, a red night light with a candle or oil lamp is thought to keep evil spirits away from the home and ward off bad luck. This use of the night light predates Christianity as well, where a lit candle was the sign of an ‘open house, ready to accept guests. The sight of a night light in a window or at a door can be a source of comfort for those returning from a late night out, as well as offer a sense of safety and protection from the unknown. Brightly colored night lights can be an enjoyable decorative addition to the home, and an interesting conversation piece. The night light can also be a tool of promotion. Many businesses, such as restaurants and bars, have night lights with the business logo positioned at their entrances as a beacon of sorts to draw in customers. No matter the use, the night light offers a warm and inviting atmosphere both literally and figuratively.
