We specialize in novelty lighting options for holiday decorating. Our retro-style bubble lights are a wonderful way to illuminate trees, wreaths, garland and more. They’re made with liquid-filled vial that is heated and lit by an incandescent light bulb. The heat created by the lamp forces the liquid to boil and bubble up, which makes it illuminate. Christmas bubble lights became very popular during the 1950's and maintained that popularity through the 1970's. Add a vintage look to your home with these festive, classy Christmas lights.
