Battery-powered light set at a low price

For those who are looking for affordable, rechargeable bike light for city traffic, this StVZO light set is the ideal companion: The 35-lux AURA 35 USB front light with its 45 meters of beam range and lateral light elements ensures a high degree of safety in road traffic. Stiftung Warentest rated the AURA 35 USB in the 9/2020 issue, giving it an overall GOOD rating (2.2), which made it the price/performance champion. The small, compact NUGGET II rear light is visible at a distance of up to 400 meters. Both lights can be mounted on your bike quickly and without tools.

Lateral visibility

Practical: Broad lighting elements on both sides improve lateral light visibility, making your ride in traffic even safer.


Rain, wind, or snow: The AURA 35 USB is protected against splashing water according to the international IPX4 standard, making it suitable for inclement weather conditions.


The AURA 35 USB has an integrated rechargeable battery. You can fully recharge the front light in less than three hours with the Micro-USB cable provided. This saves money and protects the environment.

Battery/charge indicator

An especially practical feature is the charge indicator on the operating button. It 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 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 35 USB during operation with a power bank.

Extremely easy to mount

The practical silicon handlebar bracket is permanently attached to the AURA 35 USB and ensures speedy, precise mounting to any handlebars. This allows the bike light to be mounted and removed without tools.

Switch-on protection (double click)

The front 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 school 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.
