NEW Exposure Sirius MK9 DayBright Front Bicycle Light - Black

Season:2021

Brand:Exposure

Code:EXPSIRIUS9DB

For the rider who wants a minimalist light and a high output. An array of runtime options selected via the OMS can cater for different rides and conditions, whilst side illumination maintains safety throughout the urban jungle. Also featuring our DayBright pulse pattern, this slick unit lights up the streets both day and night.

Can be helmet mounted (helmet mount sold separately).

Also available in a pack with TraceR Mk2 ReAKT for the ultimate set-up.

Intelligent Thermal Management

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.

Optimised Mode Selector

Various programmes 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.
