when were christmas tree lights invented

The first electric Christmas tree lights were invented by Thomas Edison in 1882. They consisted of small light bulbs that were strung together and wrapped around the tree. These lights were a significant improvement over the candles that were traditionally used to decorate trees at the time, as they were safer and produced a brighter light. Since then, the design and technology of Christmas tree lights have evolved and improved greatly, with more intricate designs and brighter colors available today.
