About: Starting in 18th-century Germany, the Christmas was occasionally decorated with candle. Candles for the tree were glued with melted wax to a tree branch or attached by pins. Between 1902 and 1914, small lanterns and glass balls to hold the candles started to be used. Early electric Christmas lights were introduced with electrification, beginning in the 1880s. Christmas lights (also called twinkle lights, holiday lights, mini lights or fairy lights), that are strands of electric lights used to decorate homes, public/commercial buildings and Christmas trees during the Christmas season are amongst the most recognized form of Christmas lighting. They come in a dazzling array of configurations, shapes, sizes and colors. In this fun new puzzle we feature lots and lots of colorful vintage Christmas light bulb covers. These kind of covers are used to add different colors and shapes to these kind of decorations.
