Here is the basic design i am looking at.
I am looking at doing this in 2 circuts. The circuts will be regulated by a buck regulator, and brightness will be controlled by reducing the power to the LED's. A running circut which will consist of 2 sets of 3 lux I's. Optics will be a oval on 4 of the 6, and the remaining 2 will be narrow angle. It will also consist of a foul weather mode that will turn the running circut to brake brightness. Idea taken from Euro spec. There will also be a brake circut that will consist of 3 sets of 3 lux I's. optics here will be ovals here. When not in foul weather mode the running circut will jump to brake brightness as well when braking.
Now i will not be cranking these anywhere near full brightness. They will most likely be around 60-80ma running and brake will be about 140-180ma. This should keep levels more then reasonable. I was also thinking about putting on a POT to adjust these levels if need be. Heat sinking will be done with aluminum sheeting with a heatsink into the wheel well. plenty of air flow to even overload them if wanted.
