Wireless Cycle Brake Light

  • Tells other drivers that you’re braking, helping to prevent rear shunts
  • Potentially lifesaving 2-in-1 cycle light and brake light
  • Powered by 2x AAA batteries


We all know how potentially dangerous cycling on the roads can be and how important it is to be visible to other road users.

This easy to fit, automatic wireless light from Ventus detects when it gets dark and comes on automatically after 30 seconds of cycling, plus, with Wii G-Sensor technology it detects when you are braking and a red brake light illuminates in ‘hi-intensity steady on mode’, just like a car, to prevent shunts from behind - during day or night.

At night the light operates like a conventional rear cycle light that can be set to blinking or steady, but still when you brake the ‘hi-intensity’ red light comes on.

The light turns off automatically when the bike is stationary for 4 minutes.

This excellent, unique and potentially lifesaving device is powered by two AAA batteries which allows for up to 800 hours of use when used during the day or up to 200 hours when used day and night.  With average cycling usage this should be sufficient for one year.
