Christmas lights are luminous embellishments used during the festive season of Christmas. They are often displayed around the houses, gardens and public areas during the festive season. The lights come in various colors and shapes and have a special significance in the festivities. Christmas lights had their origin in religious festivals, particularly in the celebration of Hanukkah. These lights were originally small candles lit by worshippers to symbolize the light of the Star of Bethlehem. However, over time they have become part of Christmas tradition and today they are popularly used in both religious and secular celebrations. Modern Christmas lights were first introduced to the US in 1882 in an outdoor religious event. These small bulbs, once made with carbon filaments, were the first spark of holiday decorating. Since then, these electric lights have become an integral part of Christmas decorations and festivities. Today, Christmas lights are available in a variety of colors and shapes. From candle shaped tealights to multi-colored strings of lights, the possibilities are endless when it comes to decorating for Christmas. Decorating with Christmas lights is an activity that everyone, young or old, can enjoy. It is also a great way to bring in some festive cheer to your home and neighbourhood. Christmas lights have come a long way since their genesis in religious festivals. Today, these lights bring joy and beauty to the joyous season and make it one of the most cherished times of the year.
