Rare Vintage Noma Set of 7 Red Green Yellow Christmas Bubble Lite Lights 1989

This is a rare vintage set of Bubble Christmas lights from Noma. I believe they are from 1989. When they heat up, the lights "bubble" like a lava lamp. Really cool and unique set of lights. There are 7 lights in this string. It is in its original box. Please see photos and videos. They are part of the description. Questions? Leave a comment below! S1A3
