I swear--all the lights on the tree worked last year when I put it away. About five years ago I bought one of those pre-wired, pre-lit Christmas trees. Just pop it up, plug it in, fluff out the greenery--it gets flattened in the storage box--and it just works, right?
Not if you have those little twinkle lights. I must have bought the tree just before everyone started going to LED lights. If the little twinkle light bulb comes loose, you're hosed--the whole string goes out, as well as any other strings plugged into that one. Loose or broken wire? You name it, the string is toast. Have you ever tried trouble-shooting a string of lights pre-wired onto a tree? I spent several hours on that a couple of years ago. I was successful, but I had to wonder if it was worth it.
This year, I plugged in the tree and got maybe 10% of the lights working--the very top section and about one-quarter of the bottom section. In spite of my best trouble-shooting efforts, including trying every string separately, nothing would come on. I am SO done with this. My housekeeper and I spent two solid hours unclipping and untangling all those @#$% pre-wired lights off the tree. I now have a naked tree and will happily go to Costco tomorrow to buy four new strings of small LED lights. I will take them off every year and put them back on the next. Happily.
Remember the scene from How the Grinch Stole Christmas where the whos are quickly decorating for Christmas. They bring out trees collapsed like umbrellas, pop them open, and the tree is already lit and decorated!
Thank you, Dr. Seuss.
