Sigma Aura 120 LINK Front Light + HIRO 50 LINK Rear Light Rechargeable Set

The Sigma AURA 120 LINK / HIRO 50 LINK lighting set combines a powerful front light with a compact rear light, ensuring good visibility and being seen in road traffic. Thanks to the integrated LINK technology, both lights can be connected to each other and conveniently controlled together.
 
The Sigma AURA 120 LINK front light offers an illuminance of up to 120 lux and ensures wide-area, homogeneous illumination of the road. In AUTO mode, the integrated brightness sensor automatically adjusts the light output between 40 and 120 lux to the ambient brightness. 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. 
 
The Sigma HIRO 50 LINK rear light is responsible for visibility to the rear with its intelligent brake light function. During normal operation, one LED is permanently lit. When braking, all three LEDs light up particularly brightly and signal the reduction in speed to following road users. During heavy braking, the integrated emergency brake light also activates with a pulsating warning signal. This can help to make critical braking manoeuvres recognisable early on – for example in city traffic, during sporty rides or in poor visibility conditions.
 
Via the LINK function, you can pair the front and rear lights into a convenient lighting system. Both lights can be switched on and off together using this. Furthermore, the AURA 120 LINK displays the battery level of both lights, so you can see in good time when charging is required. Both lights also have their own battery indicators. They can optionally be connected to the Sigma Ride App via Bluetooth to check the battery level and use other available functions.
 
Both lights can be attached to standard handlebars or seat posts without tools using their respective silicone mounts and can be quickly removed for charging or to protect against theft. With optionally available mounts and adapters, you can also attach the AURA 120 LINK front light to oval aero handlebars or mounts with a GoPro mount. This makes the front light also suitable for modern road bikes and bicycles with an integrated cockpit.
 
The Sigma AURA 120 LINK / HIRO 50 LINK lighting set combines high light output, automatic adjustment to ambient brightness and intelligent brake light functions with convenient, networked operation: A well-thought-out lighting solution for daily use, sporty rides and changing light conditions.
