If there is one thing that makes me want to pull out my hair, it's putting up a pre-lit Christmas tree and all of a sudden some of the lights don't work. The lights are so tightly wound around the branches it becomes an almost impossible task to figure out where the problem is on the light strands. I had that happen just the other day, a small tree that was very carefully wrapped last season, also very carefully unwrapped this year. After messing around with the strands of lights, one single strand in the middle works. But that's it. (Insert a scream here)
Some of the newer pre-lit trees now offer lights that will work even if a bulb is missing or broken. I've decided that's my next step. But Bill Quinn of Christmas Tree for Me mentioned that there are two different ways this is accomplished. The problem is I'm not quite sure how to figure out how we can tell what method is being used.
