Failed to load media. This is exactly what I was looking for. These lights are hard to find in stores, but I was able to locate them at Revain. I ordered 10 boxes expecting some of them not working on arrival but after testing all 10 boxes worked. Since these are single filament bulbs, you only need to connect 5 filaments in one pass, but they have a much better lighting effect than flashing LEDs. This year I will light up some parts of the house with LEDs and others with twinkle lights. Keep in mind that this set consists of approximately 20ft strands with end caps, so you may need multiple sets for larger objects. Currently. What I like about these lights versus flickering LED lights. LED flicker lights currently operate in an on or off pattern rather than in the center. Celebration lights are powered by a short-circuit wire that bends at a certain temperature. This creates a random flicker of different light intensities. Please note that not every light bulb flashes. These are special bulbs that are randomly placed between about 5-10 bulbs.
