Giving off an even glow that is visible even from 90 degrees to the side, the Comet is a very good rear light. There are six settings; the most impressive is overdrive where it kicked enough light out to illuminate the entire back wheel and road below.
This is ideal when angled downwards (to reduce glare), and yet it still ran for nearly two hours (one hour 52 minutes). One very good thing about the light is that it comes with a mount for the saddle rails – if you have an aero section seatpost, being able to mount it to the saddle rails is a godsend.
The only drawback we could find is that the button is difficult enough to locate when riding without wearing gloves. Stick on some gloves and it’s hit or miss.
