Emily Velasco@mds2 oh the patterns are just a byproduct of the parts I'm using. I want the tail light to blink and to do that as simply as possible, I wired a bunch of self-blinking LEDs in series with some bright LEDs. The bright LEDs are bright enough to easily be seen out on the road and the blinking LEDs cause the bright ones and themselves to blink and they have a nice side effect of limiting their own current, so I don't need to deal with a special driver or resistors.
They're not actually patterns. It's just that each blinking LED has a slightly different blink right then it's peers and after a period they end up all blinking kind of randomly. It looks like patterns though
