Sigma AURA 170 HB LINK Rechargeable Front Light with High Beam Function

The AURA 170 HB LINK from Sigma combines high light output with automatic adjustment of the illuminance, switchable high beam and intelligent networking with compatible LINK rear lights.
 
With up to 170 lux illuminance in the switchable high-beam mode, the front light provides wide-area, homogeneous, and long-range illumination. Using the wireless handlebar switch, you can conveniently switch between dipped beam and high beam without having to take your hands off the handlebars. In dipped beam mode, there are up to 150 lux illuminance. The AUTO mode offers you a clever and convenient automatic function: Thanks to the integrated brightness sensor, the front light automatically adjusts its illuminance to the ambient brightness in a range of 50 to 150 lux. This means you always have enough light when you need it, and can save the battery at the same time. This function can show its strength especially in changing light conditions, rides through the city and when setting off at dusk.
 
Thanks to the four-level battery indicator, you always have the battery level in view and can recharge in good time. This also applies to Sigma rear lights, which likewise feature the LINK function and can be paired with the AURA 170 HB LINK. You can then conveniently view the battery level of both lights on the front light. The LINK function also allows you to switch paired front and rear lights on and off together. Optionally, you can also connect the AURA 170 HB LINK via Bluetooth to the Sigma Ride app on your mobile phone. As soon as the connection is established, you can read the battery level, set lighting modes, assign device names and install firmware updates in the app.
 
You can easily mount the front light on your handlebars using the enclosed screw bracket. Thanks to the DUAL MOUNTING OPTION (DMO), you can also attach the AURA 170 HB LINK to compatible holders with a GoPro mount underneath your bike computer. This makes the AURA 170 LINK ideal for modern drop bar bikes with aero handlebars and integrated cockpits.
