Full product description

Powerful lighting and greater control while riding

SIGMA AURA 170 HB + HIRO 50 LINK is a modern bicycle light set designed for demanding users. It combines a powerful front light with intelligent rear lighting, providing better cyclist visibility and convenient operation during daily commutes, training sessions and longer rides.

The AURA 170 HB LINK front light generates up to 170 lux and 700 lumens in high-beam mode, with a beam range of up to 180 metres. The HIRO 50 LINK rear light provides visibility up to 500 metres and features a braking light function and an emergency light. Combining both devices in one set creates a functional bicycle lighting system.

AURA 170 HB LINK – powerful front light

The front light has been designed for cyclists who need powerful illumination when riding in the dark.

Key benefits:

Up to 170 lux and 700 lumens – intense road illumination in high-beam mode.
Beam range of up to 180 metres – better visibility of the route ahead.
REMOTE HB wireless remote control – convenient switching between dipped and high beam and operation of the lighting modes without taking your hands off the handlebars.
AUTO mode – the brightness sensor adjusts the light intensity to the surrounding conditions.
Four operating modes – AUTO, HIGH, MID and ECO make it easy to adapt the lighting to the situation.
LINK technology – enables control of a compatible rear light and checking its battery level.
Charge indicator – the four-level indicator makes it easy to monitor the battery status.
USB-C charging – convenient recharging, including when using a power bank.
High side visibility – the integrated LIGHT GUIDE improves the cyclist’s visibility from the side.
IP67 protection – protection against dust and the effects of immersion in water under the conditions specified by the standard.
Thanks to the mode memory function, the light starts in the last mode used. Protection against accidental activation requires the power button to be pressed twice.

HIRO 50 LINK – intelligent rear light

The HIRO 50 LINK rear light increases the cyclist’s visibility to other road users. Its functions have been designed to signal not only the presence of the bicycle, but also situations requiring particular attention.

Key benefits:

Visibility up to 500 metres – clearly signals the cyclist’s presence.
Intelligent braking light function – the built-in acceleration sensor detects braking and automatically activates the brake light function.
Emergency light – an additional warning signal.
Good side visibility – makes it easier to spot the cyclist from different directions.
LINK technology – works with compatible SIGMA LINK front lights.
Simultaneous switching on and off – convenient operation of both lights using the front light.
Battery level monitoring – the rear light’s charge level can be checked on the front light.
USB-C charging – convenient recharging.
Tool-free mounting – the flexible silicone mount makes installation on the bicycle easy.
SIGMA LINK technology – one system, convenient operation

One of the key benefits of the set is SIGMA LINK technology. It enables compatible front and rear lights to be connected into one system. This allows both lights to be switched on and off simultaneously and the rear light’s battery status to be checked without operating each device separately.

Additional convenience is provided by the SIGMA RIDE app, which allows you to connect a compatible front light via Bluetooth, check the battery status, configure lighting modes, change the device name and install software updates.

Convenient mounting and everyday functionality

AURA 170 HB LINK offers the DUAL MOUNTING OPTION (DMO), allowing you to choose between mounting on the handlebars or in a compatible position beneath a bicycle computer. The adjustable mount allows the light’s position to be adapted to the user’s needs.

Both lights are charged via USB-C. The manufacturer states a charging time of approximately 3 hours for each device. Please note that the USB-C cable and power adapter are not included as standard, so it is worth checking which accessories you already have before purchasing.
