SIGMA AURA 170 HB LINK – front bike light with high-beam function and LINK connectivity

Up to 170 lux, a range of up to 180 m and intelligent lighting for every route.

The SIGMA AURA 170 HB LINK is an advanced front bike light designed for demanding cyclists who expect excellent visibility, convenient operation and reliability when riding after dark. Powerful illumination, the HIGH BEAM function and automatic brightness adjustment help adapt the light to the current conditions on the route.

Thanks to LINK technology, the light can work together with compatible SIGMA rear lights, allowing them to be switched on and off simultaneously and their charge levels to be monitored. The wireless REMOTE HB lets you change lighting modes and activate the high beam without taking your hands off the handlebars.

Main advantages

Powerful illumination: up to 170 lux and 700 lumens in HIGH BEAM mode.
Beam range of up to 180 m: improved visibility of the road and obstacles ahead of the cyclist.
HIGH BEAM: additional illumination activated when needed using the REMOTE HB.
AUTO mode: the brightness sensor adjusts the light intensity to the surrounding conditions.
Intelligent LINK function: allows control of a compatible SIGMA rear light and monitoring of its battery level.
Wireless REMOTE HB: convenient mode switching without taking your hands off the handlebars.
SIGMA RIDE app: checking the battery level, configuring modes and updating the software via Bluetooth.
Long runtime: up to 20 hours, depending on the lighting mode.
Resistance to demanding conditions: IP67 protection rating.
Flexible mounting: the light can be mounted on the handlebars or underneath a bike computer using the appropriate accessories.
Intelligent lighting adapted to the route

HIGH BEAM

When you need more powerful illumination, simply activate HIGH BEAM mode. The beam providing up to 170 lux and a luminous flux of 700 lumens delivers additional light on dark sections of the route. The REMOTE HB allows you to conveniently switch between low and high beam.

Automatic brightness adjustment

The built-in brightness sensor adjusts the illumination to the surroundings. AUTO mode helps provide suitable visibility and use the battery power efficiently, without the need to continually change the settings manually.

Four operating modes and memory function

Choose between AUTO, HIGH, MID and ECO modes depending on the conditions and your needs. The memory function means that after being switched on again, the light returns to the last mode used. Double-clicking when switching on reduces the risk of accidental activation during transport.

LINK technology – greater control over your lighting

The AURA 170 HB LINK can work together with compatible SIGMA rear lights equipped with the LINK function, including selected HIRO and RECO LINK models.

After pairing the devices, you can:

switch compatible lights on and off simultaneously;
check the battery level of the front light and the paired rear light;
conveniently control the lighting system using the front light.
When used with the compatible RECO LINK rear radar, the integration allows more convenient control of the lighting system components.

SIGMA RIDE app

The Bluetooth connection enables the use of the SIGMA RIDE app. The app lets you check the battery level, configure lighting modes, assign a custom name to the device and install software updates.

Visibility from the side as well

The integrated LIGHT GUIDE improves the cyclist’s side visibility. This is an additional advantage when riding in traffic, especially at intersections and in places where other road users may approach from the side.

Powerful battery and USB-C charging

Depending on the selected mode, the AURA 170 HB LINK provides up to 20 hours of runtime. Charging takes place via the USB-C port and takes approximately 3 hours. The light can also be charged while in use, for example from a power bank.

The battery-level indicator makes it easier to monitor the remaining runtime and plan charging before the next ride.

Ready for demanding conditions

The housing with an IP67 protection rating provides resistance to dust and water under the conditions specified for this rating. This makes the light suitable for daily commutes, training sessions and longer rides in changeable weather.

Convenient and flexible mounting

The light can be mounted on the handlebars using a quick-release mount. The DUAL MOUNTING OPTION (DMO) allows the configuration to be changed and the light to be mounted underneath a bike computer using the appropriate accessories. The wireless REMOTE HB can be placed in a convenient position on the handlebars.
