Christmas lights are an iconic symbol of the holiday season. Every year, as the sun sets and darkness descends, cities around the world light up with millions of electric stars designed to spread cheer and and bring Christmas joy to despite the season's chill. From humble beginnings in the 19th century when the first oil lamps were set around windows and doorways, Christmas lights have come a long way. Today, the art of Christmas lighting has risen to an entirely new level, as more and more people choose to display creative holiday-themed displays in their yards, often times utilizing tens of thousands of lights. Moreover, many areas have full-blown light shows or Christmas villages featuring colorful holiday light displays that wow thousands of visitors. Christmas lights are also a great way to show Christmas spirit. Whether you opt for a subtle decoration of a few strings of bright white LEDs or a full-on technicolor extravaganza, nothing says happy holidays like a brightly lit house. Not only do they look great, but they can provide a sense of security and safety to an otherwise dark and cold night. Furthermore, in a world that could use a little more happy and joy, the beauty of Christmas lights cannot be understated. From the old-fashioned oil lamps of the 19th century to the stunning outdoor-sized spectacles of modern day, Christmas lights are undoubtedly a key part of the holiday season and Christmas joy!
