Erm... they might be a bit bright, X-ray anyone?

Those are quite bright. I don't think my new NiteRider Sol would be much chop against these.

I take it you're using a pair of the Luxeon Star 5W LEDs or similar. What voltage do these run at?

Nah... these are the Cree XR-E (Q2 bin IIRC) driven at 1000mA.

Forward voltage drop is 3.75v or something like that. The bFlex driver takes care of all that though - feed it with 9-20(ish)v and it'll do the rest.
