This lighting is equipped with the German STvZO quality mark and Raii quality mark bicycle lighting (RFK). The rechargeable AURA 45 USB illuminates with 45 Lux up to 55 meters and is therefore ideal for safety-conscious daily cyclists who also cycle regularly in their free time. New is the integrated brightness sensor, which automatically regulates the light intensity and thus enables the optimal ratio between light intensity and operating time.

In addition to the standard mode with 45 lux and 6.5 hours of burn time and the Eco mode with 15 lux and up to 21 hours of burn time, the AURA 45 USB also has an Auto Mode.

The AURA 45 USB is the first SIGMA bicycle light that thinks for itself! In "Auto" lighting mode, an integrated brightness sensor automatically adjusts the light intensity to the ambient light. This ensures the longest possible burn time.

With a homogeneous light pattern, the AURA 45 USB offers optimal visibility in the distance, to the sides, in the core, and up close, without dazzling other road users. This ensures optimal safety in traffic.

The AURA 45 USB is equipped with an Osram LED. In combination with the high-quality optics, this generates a very even light distribution over all light zones.

In Auto Mode, the integrated brightness sensor automatically adjusts the light intensity to the ambient light in a range of 15 to 45 lux.

The AURA 45 USB has an integrated battery. This is charged via the Micro-USB port, which is also possible on any PC. With the included Micro-USB cable, the headlight is fully charged again in about 2 hours.

The lithium-ion battery has deep discharge and overcharge protection. Since the battery has no memory effect, it can be fully recharged without problems.

The charging indicator on the control button indicates the battery's status. Below 70% battery capacity, the LED in the button lights green; below 30%, red. This LED also informs about the current charging status during charging. Once the battery is full, it lights green. You can charge the AURA 45 USB during use, e.g., on the go with a power bank.
