Christmas Lights are one of the most well-known and beloved symbols of the holiday season, and many people delight in decorating with the festive twinkling displays. During the Christmas season bright and colorful lights can be seen in town centers, shopping malls, along residential streets, and even in individual households . The history of Christmas lights dates back to the mid 1800s in Germany. It is said that the first decorations were shaped like candles, and were made out of wax and cardboard, with small holes pricked in to let out light. From that point the technology and development of the product began to advance, as did the popularity until eventually it became a well-established tradition. In recent times, LED lights have become increasingly common for Christmas lights displays. LEDs are bright, efficient, and long-lasting. One of the benefits of the LED technology is that it produces nearly 90 percent less heat. This makes housing the elaborate displays in living spaces simpler, as the LEDs do not need to have to concern about being a fire hazard. Christmas lights provide untold warmth and cheer to the chilly winter days, and bring families together with the spirit of the season. People will often take drives or go for walks at night, to soak in the street scenes and neighborhood decorations. And best of all, a long string of Christmas lights makes for a truly beautiful home.
