MOON Helix Sense 300 LED rear light with brake light function

MOON Helix Sense 300 is a powerful and versatile rear bike light featuring a bright COB LED, automatic brake light function, and a Stand By mode that detects when you stop.

The rear light’s maximum output is 300 lumens, and the five different light modes offer suitable options for both daytime and night riding. The Sense function detects the bike’s movement, braking, and stopping, and adjusts the light’s behavior accordingly.

The rechargeable 500 mAh lithium-polymer battery provides up to 70 hours of runtime. Charging is conveniently done via a USB-C port.

Sense function and brake light

The intelligent Sense function of the Helix Sense 300 includes several automatic features:

  • Brake light function – the light brightens when braking
  • Motion Sensing – detects movement
  • Parking / Stand By – the light turns off when stopped and activates again when you start moving
  • Brightness Function – automatic brightness adjustment
  • Auto Safe Mode – improves visibility and safety

5 light modes, Helix Sense 300 includes five different modes:

  1. DAY FLASH
  2. STEADY FLASH

The Mode Memory function remembers the last used mode.
