Does a bike need to send out light in a 360 degree cone in front of it, or does it need to send out light a little on the ground, more in a straight line, and a bit to the sides, with more light on the right side than the left?
Some funky winged wedge looking thing would seem to be the best reflector setup for that design goal.
