A whopping nine LEDs live inside this compact unit from S-Sun, powered by two AAA batteries. The middle of the unit is a reflector, and a very efficient one at that, but the main interest is those LEDs.
There are three modes of operation: flashing mode, constant mode, and then 'eagle wing' mode, where the lights are laid out in an X shape but flash up and down like the wings of a bird. It's not as impressive as it sounds. What is impressive is the brightness and the side visibility, which is only marginally overshadowed by the Cateye LD1100. The light comes with a fitting that allows it to be clipped to a bag or jacket, and in the box there's a seatpost fitting (24mm to 32mm) and a seatstay fitting (16mm to 20mm).
