antique bubble lights

These bubble lights are electric and plug in — they do not use batteries. The plug-in nightlight is described for use in a standard 120V outlet, and string options are powered by mains electricity.

Suitability varies by model. Some bubble-light strings are rated for both indoor and outdoor use (listings may be labeled “Indoor and Outdoor” or similar), and some carry UL listings for indoor or outdoor use. Check the specific product details or label for its indoor/outdoor rating.

Counts and spacing vary by strand. Example listings show 7, 12, and 15 bulbs per strand, with bulb spacing commonly ranging from about 12 inches to 36 inches. A typical range from the examples is 7–15 bulbs with 12–36 inches between bulbs.

Many vintage-style bubble lights use a bubbling liquid tube that activates as the bulb warms, producing a bubbling motion and a softly rotating or rotating-glow effect for a nostalgic animated look.

Examples list a mix of materials: bulbs and covers may be acrylic or plastic (and sometimes glass), cords and components can include rubber and metal, and strand construction commonly uses wire for the wiring and connectors.
