SIGMA LED battery front light Aura 45 USB incl. bracket | black | On/Off switch: Yes

Automatic light adjustment

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 illumination level to the ambient light. This ensures the longest possible lighting duration.

multi-zone illumination

With a homogeneous light image, the AURA 45 USB offers optimal visibility in the far, lateral, core and close range without dazzling other road users. This ensures maximum safety in road traffic.

AUTO MODE

In auto mode, the integrated brightness sensor automatically adjusts the illuminance to the ambient light within a range of 15 to 45 lux.

rechargeable

The AURA 45 USB has an integrated battery. This is recharged via the micro-USB socket, which is also possible on any PC. Using the included micro-USB cable, the front light is fully charged again in just over 2 hours.

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

battery and charge indicator

The charge indicator on the control knob tells you what state the battery is in. Below 70 percent of the battery capacity, the LED in the button lights up green, below 30 percent red. It also informs you of the current charge level during the charging process. As soon as the battery is full, it lights up green. You can also charge the AURA 45 USB while it is in use, e.g. on the road with a Powerbank
