Here is the schematic:

There is 4 functions:
* LED CHASER MODE
* BRAKE MODE
* CHASER/BRAKE MODE
* OFF. (If you want to use it in your Bycicle, you can save battery).
Now, it can be turned off, so remove the Zenner diode and resistor and build your own light for your bike.
I like cool stuff in my car, but at this point, I'm not sure what else can be done. Some ideas to improve this circuit was provided by Lito (I Should say "shOestring"?)
As a comment, I like that kind of light in my truck, but I don't use it anymore. Anyway, someday I will develop a "Music Dancing light" (something like Sound meter or lights changing while you hear your favorite CD). Another idea was to use my Led Display as Third brake light and send messages to the driver behind me.
