Moon Helix Sense 450 Rear Light

The Moon Helix Sense 450 is the most powerful light in the Helix Sense range, with up to 450 lumens from a long COB red LED. Sense mode reads the light around you and your movement, switching between night and day output on its own, lighting a brake signal as you slow and going into a parking mode when the bike stops, while standard mode gives manual settings with the Variable Lumen System, stretching day flash to as much as 150 hours.
