Lightbulb The Human Turn Signal

Now that my Stromputer is complete, I'm thinking of the next project.

Last year I saw here a cool youtube video that shows an how turn signals are embedded into a motorcycle riding jacket.

Very impressive!

But thinking functional I see a big problem:
The jacket's turn signals shouldn't be a parallel mechanism. I don't think it is practical to signal on the motorcycle and then doing the same on the jacket. It is a duality which is impractical over time and also dangerous to operate.

The other think I'm missing is brake lights - I think it is a very nice safety feature to have the back blink rapidly (i.e. modulate) when the motorcycle brakes.

So one might say, OK forget about the manual switches shown in the video. Let's connect a wire from the motorcycle to the jacket and so the human turn signals (on the rider's back) would get their input from the motorcycle.
EasternBeaver sells a tail connector that is easy to hook and provides wires for braking & turn signals (I have it installed).
That solves that duality problem, but connecting to the bike with a wire is kind of a hassle (though not a showstopper).

I'm thinking of an RF based solution.
The bike will have an RF transmitter that would send the turn signals and brake status, the an RF receiver that would reside in the Jacket with a battery.
The receiver would get the signals, and a decoder will handle the logic (turning on/off lights, blinking when braking)
The decoder can be an Arduino Lilipad and the transmitter can be another small Arduino or even some cheap analog encoder.
Another option is to prepare/modulate everything the on the transmitter side (motorcycle) and the jacket would be just a dumb analog decoder that would control lights.

The RF Transmitter:

The RF Receiver:

$8 for the RF parts, not a big deal. The Arduino Lilipad is about $20.

EDIT: Another option, use two Wixels.,, Wixel has RF on it, each is $20

Anybody interested in the project, is welcome to join it.
As usual, I go 100% open source, as in FREE, as in no $$$ profit/etc.
