No need to run twin lights up front if you get a B&M IQ Cyo. The light it puts out is plenty enough for distance illumination as well as nearfield obstacle avoidance. It will cost you about $115, and it's worth every cent.
For the back I've been happy with a combo of my PBSF blinkie as my battery backup and my B&M Seculite for a wired non-blinking taillight. The Seculite is about $35, mounts to a fender and wires into the Cyo's taillight wiring harness with ease (plug 'n' go). It uses the Cyo's standlight to stay lit at stoplights, and comes on automatically if you have the Senso (light sensing) version of the headlamp.
