Was helping my son take down the Christmas lights and had a set that quit working. As you know with most lights if one bulb is bad none of the rest will light. I found this youtube video showing how to find the bad bulb. Wish I would of found this video years ago would of save alot of time and expense. https://m.youtube.com/watch?v=lZBRYx0qXEU
