This light has the German STvZO quality mark and the Raii bicycle lighting quality mark (RFK). The rechargeable AURA 45 USB illuminates with 45 lux up to 55 meters, making it ideal for safety-conscious everyday cyclists who also regularly cycle in their spare time. A new feature is the integrated brightness sensor, which automatically regulates the light intensity, enabling the optimal balance between brightness and runtime.

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

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

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

The AURA 45 USB is equipped with an Osram LED. Combined with its high-quality optics, this generates a very even light distribution across all light zones.

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

The AURA 45 USB features an integrated battery. It's charged via the micro-USB port, which can also be done on any PC. Using the included micro-USB cable, the headlamp is fully charged in about 2 hours.

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

The charge indicator on the control button shows you the battery's current status. Below 70% battery capacity, the LED in the button glows green, and below 30%, it glows red. This LED also provides information about the current charge level during charging. Once the battery is full, it glows green. You can charge the AURA 45 USB while in use, for example, with a power bank.
