the headlight is a little low right now, but is wicked bright in reality, still not enough projection that i want. i'm going to build my own headlight next.
If the led is 3V forward biased then i will need four of them in series to properly divy the voltage.
I'm using a phillips luxeon 12V 4watt single led MR16 projector. i'm going to step it up to a 5 pad 10 watt 12V 800mA LED array and put it in my own housing.
