Christmas lights can be both blinking and non-blinking ones. If you prefer to have the flashy effect in your Christmas lights, here’s an easy fix.

Before starting your work, test the lights to make sure they are all working properly. Take the string of the lights and unplug it to avoid electric shock. Choose a bulb from the start of the string and remove it from the string.

Be careful while removing the bulb from the string. Pull out the base with the bulb while removing it.

Christmas bulbs come with some spare bulbs in the packaging. Among the spare bulbs, you may find a red or silvertip marked bulb. Now, this bulb works like magic and it can make all the bulbs blink.

Take this bulb and place it on the string from where you removed the bulb previously. After that, plug in the bulb string. Within a few minutes, you’ll notice the flashy effect in your Christmas lights.

In case you see somewhere the light is not blinking, remove a bulb from there. And then replace it with one of the marked bulbs. You’ll see the magic again.
