Surprise! Surprise! 
Thomas Edison, the inventor of the first successful practical light bulb, created the very first strand of electric lights. During the Christmas season of 1880, these strands were strung around the outside of his Menlo Park Laboratory. Railroad passengers traveling by the laboratory got their first look at an electrical light display. But it would take almost forty years for electric Christmas lights to become the tradition that we all know and love.

Is this your house??? By the way, I found our puppy entangled in one of the bush lights (a web of lights that goes over bushes) this morning. She had been trying to chew her way out of them (thank goodness they were off!). I did feel sorry for her (after I got over my frustration with her!).
