SIGMA AURA 120 LINK – intelligent bicycle lighting with up to 120 lux

Brightness, smart features and comfort on every ride.

The SIGMA AURA 120 LINK is an advanced front bicycle light that combines powerful illumination with intelligent LINK connectivity and automatic brightness adjustment according to ambient conditions. It offers a luminous flux of 220 lumens, a beam range of up to 130 metres and up to 18 hours of operation on a single charge. It is an excellent choice for both everyday commuting and longer cycling trips.

Thanks to the LINK function, the light can be connected to compatible SIGMA rear lights to control the lighting together and conveniently monitor the battery charge levels. USB-C charging, intuitive operation and tool-free installation make the AURA 120 LINK a practical solution for demanding cyclists.

Key benefits

Up to 120 lux – effective illumination of the road and surroundings when riding after dark.
Beam range of up to 130 m – better orientation on the route in conditions of limited visibility.
Intelligent LINK function – simultaneous switching on and off of compatible front and rear lights, as well as monitoring of their battery levels.
Automatic AUTO mode – the brightness sensor independently adjusts the light output from 40 to 120 lux, helping to save energy.
Up to 18 hours of operation – long runtime depending on the selected mode.
USB-C charging – convenient power replenishment; a full charge takes approximately 3 hours.
LIGHT GUIDE side visibility – additional light elements improve the light’s visibility from the side.
Four light modes – AUTO, HIGH, MID and ECO allow the illumination to be adapted to the situation.
Mode memory function – when switched on again, the light restores the last mode used.
IP44 splash resistance – ready for use in rainy weather as well.
Quick, tool-free installation – the flexible silicone mount with quick-release mechanism makes it easy to attach and remove the light.
Intelligent LINK connectivity

Connect the AURA 120 LINK to a compatible SIGMA rear light to use a convenient lighting system. Switch both devices on and off simultaneously and monitor the charge level of both batteries. The light is also compatible with SIGMA RECO LINK radar rear lights.

Automatic brightness adjustment

The integrated brightness sensor adjusts the light intensity to the ambient conditions within a range of 40 to 120 lux. AUTO mode helps maintain suitable illumination and use the battery energy more efficiently.

Convenient operation and the SIGMA RIDE app

Four light modes enable the light’s operation to be quickly adjusted to current needs. Double-pressing the button while switching on prevents the device from being activated accidentally, while the memory function restores the last selected mode.

When connected via Bluetooth to the SIGMA RIDE app, you can check the charge level, change the mode settings, assign the device a custom name and install software updates.

Mounting suited to your bicycle

The flexible silicone mount enables quick, tool-free installation and adjustment of the light’s position. For those who prefer a tidy cockpit, the optional AURA OUT FRONT MOUNT is available, allowing the light to be positioned centrally in front of the handlebar, below the bicycle computer.
