Sigma AURA 90 Front Light + HIRO 50 Rear Light Rechargeable Set

The Sigma AURA 90 / HIRO 50 lighting set has a long burn time and combines a powerful front light with a rear light that is equipped with emergency and brake light functions and is intended to ensure good vision and visibility in road traffic.

With up to 90 lux illuminance, the front light ensures large-area, homogeneous illumination and reliable visibility in the dark. The AUTO mode offers you a clever and convenient automatic function: Thanks to the integrated brightness sensor, the front light in this mode automatically adjusts its illuminance to the ambient brightness in a range of 20 to 90 lux. 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. Thanks to the multi-stage battery indicator, you always have the battery level in view and can recharge in good time. 

You can easily mount the front light on your handlebars using the silicone bracket, which can be attached to all common handlebar diameters. Once mounted, you can quickly remove the AURA 90 from the bracket for charging or protection against theft and put it back on again. With the optionally available brackets and adapters, you can also attach the front light to oval aero handlebars or brackets with a GoPro mount. This makes the Sigma AURA 90 ideal for modern drop bar bikes with integrated cockpits.
 
But it is not just about being able to see well, but also about being seen well: The HIRO 50 from Sigma is equipped with emergency and brake light functions for this purpose, to enable high visibility in tricky situations. During braking, all three LEDs of the rear light shine particularly brightly, which can alert following road users to your rapid reduction in speed. In addition, the light has an integrated emergency brake light, which reacts to heavy braking with a pulsating warning signal. This allows critical braking manoeuvres to be recognised earlier – especially in dense city traffic, during fast road bike rides or in poor visibility conditions.
