Technology

  • SMART Brake Function - When the light senses a braking motion, it will switch to its maximum 30-lumen output for a short time to alert road users behind you. When normal motion is resumed, the light reverts to the initial mode. When in SMART mode, if the light is motionless for 2 minutes it will automatically switch off to save battery. When motion is detected the light will turn back on and resume normal operation. SMART mode can be turned on or off as needed.

Great light

Light, smart and super bright

Could be better

Too many small, separate parts - a band, a spacer and the light unit so if regularly take it on and off will lose something eventually. Annoying that light itself needs a long hold to switch on and another to get into smart mode. Hard to do in gloves and takes too long.
