Blue Light Bulbs

C-7 & C-9 Transparent Blue Christmas Light Bulbs.  Replace your old bulbs with a set of brand-new Candelabra Lights.  Choose between Twinkle or Steady: Twinkling bulbs have a filament inside the bulb that when heated up by the socket, breaks apart and causes the illusion of a blinking/flashing/twinkling light bulb. Steady Bulbs stay on continuously while plugged in.  No flashing on and off.   Bulb Specs: C-7 (E12) or C-9 (E17) brass base sockets.  For more information regarding the difference in size, click here C7 - 1.5in long X .825in diameter C9 - 2in long X 1.125in diameter Screw-In Replaceable Each box contains 25 bulbs Transparent colors - Glass bulbs are clear blue, triple-dipped in blue paint for deeper, darker colors that last longer over the years Candelabra Shaped - They look like sparkling candles in the night!
