DayBright Pulse

Bespoke pulse pattern designed for daylight use which is more conspicuous than a regular pulse and visible from over a kilometre away, even in the brightest conditions. DayBright mode will get you noticed. Be Seen Be Safe.

Optimised Mode Selector (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.

Intelligent Thermal Management (ITM)

Patented circuitry within the light will reduce power to the LEDs, if they go beyond the optimum temperature, keeping the light as efficiently as possible to maximise output and battery capacity.

Smart Port Technology Plus (SPT+)

Smart Port+ enables the charge port to accept additional accessories such as rear lights, remote switches, Support Cells and use your light as a power bank to charge USB devices.

Cable Free Design (CFD)

The battery is housed within the body of the light so no cables or separate battery units are giving a neat solution with fewer opportunities for water ingress, mounting difficulties and crash damage. Combined with the renowned quick-release handlebar bracket lights are easy and quick to mount with rock solid attachment.

Fuel Gauge

The remaining runtime of the light system is easily monitored at a glance so you’re not caught out. The colour feedback is also used for mode selection, before defaulting back to the runtime.
