I run a Cygolite DualCross 300 up front and a single Planet Bike SuperFlash for a tailight. Both are excellent lights. The Cygolite DualCross 300 beam tends to get washed out on brightly lit city streets. That's not a problem as the streetlights provide the light to see by. On poorly lit streets, the Cygolite DualCross 300 provides plenty of clean bright light to see by. The Planet Bike SuperFlash replaced my Cateye LD 1000. I prefer it for its compact size and extremely bright flashing led.
