Christmas lights are one of the most iconic symbols of the holiday season. For generations, people have adorned their homes and neighborhoods with festive lights that sparkle, twinkle, and add a cheery atmosphere to the festivities. Christmas lights usually come in strands of bright colors like white, green, yellow, blue, red, and orange, and are used to decorate houses and gardens. From a single bulb to hundreds, the various colors, sizes, and shapes of lights bring joy, cheer, and warmth to any holiday. The popularity of Christmas lights can be traced back centuries ago to a tradition of lighting small oil lamps to ward off evil during the winter. It wasnt until the 20th century, however, that electric Christmas lights became widely available and popular. In 1903, President Roosevelt lit the first string of electric lights on the White House Christmas tree, and from then on the use of electric Christmas lights spread rapidly. Today, Christmas lights can be found in every shape and size, from mini strings to elaborate designs that can last for an entire block. But whatever style you choose, the twinkle and light of Christmas lights will always provide warmth and joy during the holiday season.
