Another vintage find

I had this electric device laid out in the basement. I tested it down there, and it didn't do anything, so I thought it didn't work. It says Sound Flash on it, and warns to use for Xmas Strings. I brought it upstairs, and learned a little more about it. I set my tree up, and thought I'd try it on the tree. The darn thing works! It is sound activated, sort of an early application of The Clapper, so the lights flicker with every sound. I was surprised it worked. My daughter came over today, and I showed it to her, in case she might like to use it for her tree. She watched it for a few seconds and said, "Well, it's cool, but I'd feel like I was in Stranger Things." I started laughing and she said, "Blink once for Yes, twice for No." lol

I posted it on Imgur. Here is a link. It is too fun not to share! https://imgur.com/a/Gt9jk2k
