Flashing light strings are always a big hit on Christmas trees and projects.
An easy way to add twinkle, the solution may already be in the little cellophane envelope that came with your set of mini lights!
In addition to an extra bulb, you might have a red tipped bulb!
Install it anywhere in the light string and after the bulbs warm up for a minute, the entire string will flash on and off!
Mix a flashing string with several steady-on strings to add “light texture” to your Christmas tree.

Ok I did the right thing with the bulbs with the red stripe and most of my bulbs are still not flashing. Can you please tell me why??? Thank you.
That is a puzzle.
If only a portion of your lights is flashing, they may be made in more than one circuit. If that is the case you need to put a flasher bulb in each section.
Not all light sets are designed to flash. If this doesn’t work, that may be the case with your string.
