Bright rear light with flash function

The small, rechargeable NUGGET II FLASH rear light, with its 400 meters of visibility range, three light modes (including Flash mode), and a burn time of up to eight hours, provides serious safety benefits in road traffic.

Three light modes

Burn time ≤ 5 h

high power

Visibility range ≤ 400 m
Burn time ≤ 2 h

high power flashing

Visibility range ≤ 400 m

The NUGGET II FLASH enables cyclists to choose from three light modes to adjust luminosity and battery life. In Standard mode, the rear light can operate for up to five hours, in High Power mode up to two hours, and in High Power Flashing mode up to eight hours.


The NUGGET II FLASH not only is able to light up constantly, but also has a flash mode. High Power Flashing mode lasts for up to eight hours, drawing attention to the cyclist with its pulsing LED.

Fresnel lens

The Fresnel lens specially developed by SIGMA is ideally suited to the NUGGET II FLASH’s design. Thanks to its ring-shaped structure, it ensures good light distribution in extremely small spaces. Its lateral visibility, which goes well beyond 220°, is particularly noteworthy.


The NUGGET II FLASH 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 FLASH 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 FLASH’s battery status and charge level so that you have no unpleasant surprises on your bike tour.


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

Quick to mount

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