90s vintage holiday lights new in box, electronic musical Christmas carols color chasing light set

Early electronic Christmas lights, 1990s - these play Christmas carols and blink different colors with the music (wonderfully high tech back in the day, and wonderfully nostalgic now!).

This set has never been out of the box. I just plugged them in for testing just as they are, and have a video of them lighted and playing (they work fine) which I'll probably put in Instagram - they're fun to watch and sound perfectly like Christmas.
