SIGMA AURA 100 LINK – intelligent bike lighting that keeps up with your ride

More light. More control. More confidence on every route.

Discover the SIGMA AURA 100 LINK – a modern LED front bike light that combines powerful illumination with intelligent features and convenient operation. With brightness of up to 100 lux, a beam range of up to 110 metres and automatic adjustment of the light to ambient conditions, you can ride comfortably after dark, on your daily commute, during road cycling training and on longer trips.

The AURA 100 LINK is more than a classic bike light. Thanks to SIGMA LINK technology, it works with compatible rear lights and the SIGMA RECO LINK radar, creating an intelligent lighting system that makes it easier to control your equipment and lets you focus on riding.

Intelligent light that adapts to you

The automatic AUTO mode uses a brightness sensor to adjust the light intensity to the surroundings. Changing conditions on the route, entering a tunnel or dusk setting in do not have to mean constantly switching modes manually. This convenience works equally well in the city and during dynamic rides outside it.

Up to 100 lux – powerful illumination of the road ahead.
Beam range of up to 110 metres – better visibility of the route ahead.
Uniform beam of light – comfortable illumination while riding.
Light distribution compliant with StVZO requirements – designed to provide appropriate road illumination and limit glare.
LIGHT GUIDE – improved side visibility that helps attract the attention of other road users.
SIGMA LINK – front and rear light in one system

Connect the AURA 100 LINK via Bluetooth to a compatible SIGMA LINK rear light or SIGMA RECO LINK radar rear light. This gives you more convenient lighting operation and easier control of its status.

All the most important information under control

The integrated five-level battery indicator lets you quickly check the light's charge level and, when using LINK, that of a compatible rear light or radar. The display also shows the active lighting mode and charging progress.

This makes it easier to plan your next route and reduces the risk of being caught out by a discharged battery.

Power for short and long rides

The efficient lithium-ion battery provides up to 12 hours of runtime in ECO mode. Four lighting levels are available, allowing you to adjust the light intensity to your current needs and riding time.

Standard mode: up to 3 hours.
Mid mode: up to 4 hours.
Low mode: up to 6 hours.
ECO mode: up to 12 hours.
Charging via USB-C takes approximately 4.5 hours. Importantly, the light can also be charged while in use, for example with a power bank. This is a practical advantage during longer trips and bikepacking.

Easy mounting and ready for changing weather

The flexible bracket enables quick, tool-free installation, while the quick-release mechanism makes it easy to remove the light. The well-designed OUT FRONT construction also helps keep the cockpit tidy and gives the bike a modern look.

IP44 protection means resistance to splashing water, so the AURA 100 LINK is also suitable for riding in changeable weather.

Designed for different riding styles

Whether you commute to work every day, train on a road bike, explore gravel roads or plan a longer bikepacking trip, the SIGMA AURA 100 LINK offers a combination of powerful light, intelligent control and practical solutions.
