Rear lighting that flares up automatically under braking. It can also intelligently adapt to the surrounding ambient light conditions to maintain maximum contrast and visibility, for example brightening for street lit areas and moving into sunlight from shade.


Various programs in the lights can easily be selected to offer a choice of run times and modes so you can find the right one for your ride, be it an all-night adventure or an intense blast.


Patented circuitry within the light will reduce power to the LEDs, if they go beyond the optimum temperature, keeping the light as efficient as possible to maximise output and battery capacity. Once the light has cooled, the power is automatically restored.
