It’s your choice: in addition to Auto mode with its automatic brightness adjustment, the AURA 45 USB features other light modes that you can activate as you desire. In standard mode, the StVZO bike light can deliver 45 lux for 6.5 hours and in Eco mode 15 lux for a whopping 21 hours.

Automatic light adjustment

The AURA 45 USB is a bike light that follows the plot. In the “Auto” lighting mode, an integrated brightness sensor automatically adapts illuminance to ambient light (in a range from 15 to 45 lux). This maximises the time you can bike with optimal luminosity.

Lateral visibility

Broad lighting elements on both sides ensure improved bicycle light visibility. This makes you easier to see and keeps you even safer in road traffic.


The AURA 45 USB will accompany you on all your bike adventures. It is resistant to splashing water in accordance with the international IPX4 standard, so it can be used in all types of weather.


The AURA 45 USB has an integrated rechargeable battery. The Micro-USB cable supplied charges the front light completely in a little over two hours. This saves money and protects the environment.

Battery/charge indicator

Practical: The charge indicator on the operating button shows the battery status. If the battery capacity is below 70 per cent, the LED in the button lights up green, and if capacity is below 30 per cent, it lights up red. You can also see the current charging status at any time during the charging process. As soon as the battery is fully charged, it lights up green. If you are in a hurry, you can charge the AURA 45 USB during operation.

Quick and simple mounting

The practical silicon handlebar bracket is permanently attached to the AURA 45 USB and ensures speedy, precise mounting to any handlebars. The bike light can thus be mounted and removed quickly and without tools.

Switch-on protection (double click)

The bike light is switched on with a double-click and switched off with a long button press. This function prevents inadvertent switching on (when it is in the user’s gym bag, for example).

400-meter visibility range

When lit, the NUGGET II rear light is visible to others on the road at a distance of 400 meters, ensuring a high level of safety in road traffic. Its outstanding lateral visibility, well beyond 220°, is particularly noteworthy.

Fresnel lens

The Fresnel lens specially developed by SIGMA is ideally suited to the NUGGET II’s design. Thanks to its ring-shaped structure, it ensures good light distribution in extremely small spaces.


The NUGGET II has an integrated lithium-ion battery. The USB port for recharging is well covered at the bottom of the rear light and thus protected from dust and splash water. The supplied Micro-USB cable can be used to charge the NUGGET II completely in two hours. This saves money and protects the environment.

Two-level charge indicator

There are two symbols above the lens. This enables you to keep an eye on the NUGGET II’s battery status and charge level so that you have no unpleasant surprises on your bike tour.

Excellent price/performance ratio

Good quality does not always have to be expensive. The NUGGET II is one of the most affordable USB taillights on the market and is available in sets with various SIGMA front lights.


The StVZO NUGGET II rear light is protected against splashing water according to the international IPX4 standard, making it well-suited to inclement weather conditions.

Quick to mount

The two O-rings included in delivery can be used to attach the NUGGET II to all common seat posts quickly and without tools, so it can be used with different bikes.
