SIGMA AURA 100 + HIRO 50 LINK – intelligent bicycle light set

More light, greater visibility and full control while riding.

Improve your visibility on the road with the SIGMA AURA 100 + HIRO 50 LINK bicycle light set. It combines a powerful front light with an intelligent rear light to make riding safely in the dark easier – during daily commutes, training sessions and longer cycling trips.

The AURA 100 LINK front light offers brightness of up to 100 lux and a beam range of up to 110 metres, helping you see the road ahead. The HIRO 50 LINK rear light increases the cyclist’s visibility with a visibility range of up to 500 metres, while the integrated brake light and emergency light functions attract additional attention from other road users.

Intelligent lighting that works with you

Thanks to SIGMA LINK technology, you can control a compatible rear light directly from the AURA 100 LINK front light. Switching both lights on and off becomes easier, and the rear light’s battery level can be checked from the front light. Fewer actions to perform, more attention focused on riding.

AURA 100 LINK – powerful light and automatic adjustment

The front light was designed for cyclists who expect powerful illumination and convenient operation.

Up to 100 lux and a range of up to 110 m – good road illumination when riding in the dark.
Intelligent AUTO mode – the brightness sensor automatically adjusts the light intensity to the ambient conditions.
Four lighting modes besides AUTO: STANDARD, MID, LOW and ECO, allowing you to adapt the power to the situation and extend the runtime.
Up to 12 hours of runtime – in ECO mode, ideal for longer rides.
Side visibility – the Light Guide design helps improve the cyclist’s visibility from the side as well.
USB-C charging – convenient recharging, with a full charging time of approximately 4.5 hours.
Battery status indicator – makes it easier to monitor the energy level.
IP44 protection – protection against splashing water.
HIRO 50 LINK – attract attention while braking too

The HIRO 50 LINK rear light helps ensure the cyclist is visible from behind and from the side. Its intelligent functions support communication with other road users, especially in situations requiring a quick reaction.

Visibility up to 500 m – helps other road users notice the cyclist earlier.
Intelligent brake light – the integrated sensor detects braking and automatically activates the appropriate light signal.
Emergency light during hard braking – further increases the attention drawn to the cyclist in demanding situations.
Side visibility – improves the bicycle’s recognisability from different directions.
Up to 11 hours of runtime – long operating time on a single charge.
USB-C charging – full charging in approximately 3 hours.
IP44 protection – resistance to splashing water.
Compact design and tool-free mounting – easy preparation of the bicycle for riding.
Quick installation and everyday convenience

Both lights were designed for easy operation. No tools are required for installation, and the practical mounts allow you to quickly prepare the bicycle for riding and remove the lights after the ride. USB-C charging makes it easier to keep the set ready for use.

The set meets the requirements of the German StVZO approval for bicycle lighting. The IP44 protection rating allows the lights to be used in conditions with splashing water, for example when riding in the rain.
