  • TAP: Quickly switch between modes on helmet lights by tapping either the body of the light or the helmet without needing to locate the function button for fast control to match the pace of the trail. Three sensitivities allow greater versatility.
  • ITM: 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 maximize output and battery capacity. Once cooled the output is automatically restored.
  • OMS: 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.
  • SPT+: Smart Port+ enables the charge port to accept auxiliary accessories such as rear lights, remote switches, Support Cells and use your light as a power bank to charge USB devices.
  • Fuel Gauge: Using a traffic light system remaining runtime is easily monitored at a glance so you're not caught out. The color feedback is also used for mode selection, before defaulting back to runtime.
