It was a good tree.
I disposed of several strands of old incandescent lights to make room for the new LED lights that I bought in the box. There are still more incandescent strands that we haven't used in a few years, but we'll hang onto them for a while longer in case we decide to decorate the windows again. And we replaced some bulbs in the aging string of sequencers that we do use every year, so it's all working again.
I've been looking for LED sequencers, but haven't seen them yet. Maybe next year.
