They change color from green to yellow to red or something like that. When you stare and blink at the lights, if it is green, you can see red when you blink. How do they work? The lights have a little box attached by the plug-in.

Yes there is a Green and Red Led inside "EACH" Bulb....
But did you notice there isn't a separate wire for Each bulb???
Here's how they make Different Colors.....
They flip the Positive and Negative polarity back and forth on the wire....That little box does the flipping....
So if one wire is positive....IT's Red.
Then that same wire is negative...It's Green..
If they split the time evenly then IT LOOKS YELLOW!
But they gotta flash it back and forth for yellow to appear...over 25 times a second minimum....otherwise you'll see flicker...
Faster makes flicker disappear.....That's the box's job (it's a microprocessor)
When you "Blink" at the lights....guess what....you're "capturing a short "slice" of color....that color can be Red.....or it can be Green....
If you do the eye-blink trick with a fan....the blades can seem to stop...

Each light has a green and red LED in it. When you turn both on, they create a yellow color. The box adjusts which LED (green or red) is turned on and to what amount to vary the colors.
The red you see when you blink is probably from your personal optic system and not the LED's. If you stare at a red, white, and blue flag, then close your eyes, it won't be red, white, and blue but green, black, and orange.

My house is defined in pink/white icicle lighting fixtures, my living house windows in blue, and my fenceline in multicolor. I actually have a santa clause and reindeer in the front backyard on one area and a blowup snowman family members on the different, and a blow up candycane archway that proclaims seasons greetings. looks large.
