If you are working on multiple strings of lights, lay the strings side by side.
Remove this bulb from the light string, and set the bulb aside.
Most strings of non-blinking bulbs come with one or more blinking bulbs included. Non-blinking bulbs look similar to blinking bulbs; however, the blinking bulbs have red or silver paint at their tips. Blinking bulbs can be purchased separately if necessary.
After adding the blinking bulb, plug in the light string. Within several seconds, the lights should start blinking. If only half of the lights blink, you have a string of lights with two circuits. To create an entire string of blinking bulbs, remove the bulb next to the last light that is blinking on the string, and replace it with a blinking bulb.
