Aerolux Light Corporation (New York City) was a manufacturer of figural, gas-discharge light bulbs from the 1930s through the 1970s. US Patents dating back to the 1930s. The bulbs contained low pressure gas, either neon or argon, or a mixture of the two. Also within the bulb were metal sculptures coated with phosphors. These phosphors fluoresced when excited by glow discharge. Info from Wikipedia. This one has a holly sprig, and, "Merry Xmas" inside. It fits a standard size light bulb socket. The electrical base in the photo is just for display purposes, and the price listed is for the bulb, ONLY. If you would like the display base too, email me.
I currently have several other vintage, Christmas, Halloween and Easter items in my shop, and am happy to combine shipping. To see them all, type, "holiday" in the California Girls search box at the top of the page.
If you are ordering more than 1 item from my shop, wait to pay until I send back an invoice with the combined shipping discount.
