how to make my christmas tree lights blink

It sounds like you're trying to get your Christmas tree lights to blink. Have you tried plugging them in? If they still aren't blinking, there may be a problem with the wiring or the electrical outlet. You can try testing the lights with a multimeter to see if the circuit is complete or if there is a short. You can also try checking the fuse box to make sure that the fuse is not blown. If the lights still don't blink, you may need to replace them.
