After a few electrical glitches and a wasted strand of lights, we're up and running with our Christmas lights outside (and a fuse hasn't blown yet!) Living in a 75+ year old home, the electrical panel and fuse box isn't the greatest. For years, every time we used the hair dryer in the bathroom, the Christmas lights would blow! I think we solved that little issue by hooking the lights up to our pool pump outlet!
