How to Make Little Christmas Lights Blink
- 1). Lay out the first set of lights that you want to make into blinking lights. Untangle any snarls and knots, so that all bulbs can easily be viewed.
- 2). Plug in the lights. Make sure the entire strand is working. If any lights are out, this is a good time to replace them.
- 3). Unplug the lights. Remove one bulb, usually the one closest to the plug. This makes it easy to find if it burns out. Replace it with a blinker light bulb. These normally come as spare bulbs in the package with the light set and are clear bulbs with red or silver tops.
- 4). Plug the lights back in. At first they should all come on. As the lights warm up, the blinker light will heat up and an internal filament bends. This breaks the circuit and causes all of the lights to go off. It cools rapidly, the filament straightens, and all of the lights come on again. This cycle repeats until the blinker bulb is worn out and stops working.
- 5). Check to see that all of your lights are blinking. If you have some that are and some that aren't, your lights are on more than one circuit. Replace one of the non-blinking lights with a blinker light bulb, and test the strand again. Continue doing this until all of the lights in the strand are blinking.
