Last week I listed a string of lighted glitter bells. I looked up the history on these lighted bells and discovered that they were made by G.E. GE was known as the best novelty light bulb maker so it is no surprise that these were made by them.
The factory lists them as Lighted bells, #C7-LB. They were made from 1972 -1977. These ornaments had a C-7 transparent finish bulb cemented inside a glitter coated plastic bell, which makes replacing the bulbs a challenge. This link gives a page of step by step instructions for how to do so.
