Sigma Sport Aura 45 Front light

The rechargeable AURA 45 USB shines a good 55 meters with 45 lux and is therefore ideal for safety-conscious everyday cyclists who also regularly do their leisure activities by bike. A new feature is the integrated brightness sensor, which automatically regulates the illuminance and thus enables the optimal relationship between illuminance and duration of the light.

In standard mode, the AURA 45 USB lights up with 45 lux for around 6.5 hours; in eco mode with 15 lux, it lasts for 21 hours. In addition, it has the auto mode with automatic brightness adjustment.

Automatic light adjustment

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

Multiple zone illumination

With a homogeneous light image, the AURA 45 USB offers optimal vision in the far, side, core and close range without dazzling other road users. This guarantees the highest level of safety in road traffic.

Auto mode

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

Side visibility

Wide side lighting elements on both sides ensure improved visibility of the bicycle light in traffic.

The AURA 45 USB has an integrated battery. This is reloaded via the micro USB socket, which is also possible on any PC. With the included micro-USB cable, the front light can be fully recharged in a good 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 charging indicator

The charge indicator on the control button 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 about the current state of charge while charging. As soon as the battery is full, it glows green. The AURA 45 USB can also be charged during operation, e.g. B. on the go with a power bank.

Switch-on protection

The bike light is switched on with a double click and off again with a long press. This function prevents unintentional switching on, e.g. B. in your pocket.

Weatherproof

The AURA 45 USB is protected against splash water in accordance with the international IPX4 standard and is therefore also suitable for bad weather conditions.

Easy construction

The practical silicone handlebar bracket is firmly connected to the AURA 45 USB and guarantees fast and precise attachment to any bicycle handlebar. So the bike light can be assembled and removed without tools. The AURA 45 USB is also compatible with other SIGMA holder systems, such as the screw bracket and the universal helmet holder.

OSRAM LED

The AURA 45 USB is equipped with an Osram LED. In combination with the high-performance optics, this creates a very even distribution of light across all light zones.
