These sets are becoming very difficult to find. They look like this.
I've already had one set reach of end of life and they are not repairable. And this comes from someone who has at least 50 Christmas light sets from the late 60's, early 70's and they take constant maintenance
These make up part of the fireplace mantle decorations. I have many fond memories of watching TV in the living room with Mom and these would glowing in the dark. I would greatly appreciate any leads.
