control the Light Module on an 2006 BMW

Hello.
I need necessary hardware to control the Light Module on an 2006 BMW, especially to activate the brake lights.
Can this be done by any of arduino obd II projects?

Why not just wire up a switch in parallel with the brake pedal switch?

I want to automatically turn on brake flashes on certain decrese of the speed when not pressing the brake pedal.

I can only assume you mean "over certain values of deceleration".

yes. exactly.

So.....
What have you gotten so far?

Hi,

Check that it is legal to do that with RED brake lights.

Usually you are only allow you to flash AMBER lights on a vehicle.

Otherwise your idea of proportional brake light flashing with deceleration would be in most cars by now.

I was hoping he meant a track car...

Any form of modification to a car for the public road (with an MOT) must have any modifications put through MOT and Insurance...so I went for the "benefit of doubt".

The car will only run on a private track to demonstrate the concept. it's a project i have at the university. I'm studying aerospace propulsion systems and have almost no electronics background, but i see this as an opportunity to catch up. ... so... so far I got nothing. On a second note, I am thinking to use:

OPTION A:
Sparkfun (or other) CAN Bus Shield;
Arduino UNO R3.

OPTION B:
OBD-II Telematics Advanced Kit.

Why do you not just use a relay and an accelerometer?

I want to make an plug&play device to be able to removeit and install it on another car right away.

Interesting... Thanks.
