Moon Helix Sense 300 Rear Light

The Moon Helix Sense 300 has the same Sense mode as the Helix Sense 450 in a smaller, lighter body with up to 300 lumens. 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 for longer run times.
