Boost up your ride

Premium battery-powered light with an elegant design

This StVZO light set gives you the optimum equipment for rides in the dark. The stylish, 80-lux AURA 80 USB has a beam range of at least 90 meters and improves side visibility with the “Light Guide”. LED indicators on its top give you information about the remaining battery charge level and the current lighting mode. Stiftung Warentest rated the AURA 80 in the 9/2020 issue, giving it a GOOD rating (2.0). The small, compact NUGGET II rear light is visible at distances of up to 400 meters, ensuring a high level of safety in road traffic. Both lights can be mounted on your bike quickly and without tools.

Four modes to choose from


Effectiveness ≤ 80 lux
Burn time ≤ 4 h


Effectiveness ≤ 60 lux
Burn time ≤ 5 h


Effectiveness ≤ 40 lux
Burn time ≤ 6,5 h


Effectiveness ≤ 20 lux
Burn time ≤ 15 h

You can use the four light modes to decide for yourself how much lighting power to use and how long you want to ride. At the highest level, the front light battery is good for more than four hours. In twilight or on well-lit streets, you can use Eco mode, which provides sufficient bike lighting for up to 15 hours.

The AURA 80 USB’s integrated lithium-ion battery can be charged at any time with Micro-USB. In a maximum of 4.5 hours, your front light is fully charged and functional. This saves money and protects the environment.

Multi-level indicators

Exceptionally practical: The AURA 80 USB is equipped with multi-level indicators for battery capacity and luminosity. Yellow LEDs on the top show you the currently selected light mode. The green LEDs inform you precisely about the remaining charge in your StVZO bike light. If the charge level falls below about 10 percent, the AURA 80 USB automatically switches to Eco mode to keep you out of the dark on your bike tour. If you are in a hurry, you can charge the front light even during operation.


The lateral Light Guide is not just a visual highlight. The two additional LEDs ensure significantly higher lateral visibility. Other road users can thus see you easier.

High-quality design

Innovation meets modern design. The Light Guide, the battery and light mode indicator, and the housing with its aluminium application give you not just a bike light, but an optical highlight. And that is not all: With all its components and considerable luminosity, the AURA 80 USB, including its bracket, weighs only 119 grams.


No excuses, even when the weather is bad: The AURA 80 USB is protected against splashing water according to the international IPX4 standard, making it suitable for bike tours in inclement weather conditions.

Simple mounting

The practical silicon handlebar bracket is permanently attached to the AURA 80 USB and ensures speedy, precise mounting to any handlebars. This allows the bike light, which complies with German road traffic regulations (StVZO), to be mounted and removed without tools.

Switch-on protection

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 pocket, 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.
