Here is a simple, very bright purple LED LilyPad. Light up the night!
LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable!
Note: The purple LED has a much higher voltage drop than other LilyPad LEDs so it will be dimmer than the others.
