Moon Sport Helix Sense (450lm)

The Helix Sense 450 is quite possibly the brightest and most feature packed rear light ever made. The unique Sense mode includes a braking light which increases brightness when slowing down, brightness sensing which automatically switches between daytime flashing and night mode and parking mode which automatically turns the light to standby mode when no motion is detected. In addition, the Helix Sense 450 also has a group ride mode to allow you to be seen on group rides without dazzling your riding friends. Specification COB red LED Max.
