Bicycle lights SIGMA Aura 80 + Nugget II set — front LED 80 lm, USB rechargeable, aluminium/plastic housing, battery-powered

The SIGMA Aura 80 + Nugget II set combines a bright USB-rechargeable front LED and a compact rear red LED to provide balanced bicycle lighting for commuting and urban rides. The Aura 80 front lamp delivers 80 lux with a beam reach up to 90 meters and offers four light modes to balance runtime and output. The front housing uses aluminium and plastic for a lightweight but durable construction, while the Nugget II rear light provides steady and flashing red output for visibility. Both lights use built-in rechargeable batteries with USB charging and offer simple status indicators for battery level and selected mode.

Advantages

The front light supplies a concentrated 80 lux beam that meets high visibility standards and provides long-range illumination for evening and low-light conditions. The lateral Light Guide increases side visibility while the top-mounted LED indicators show battery charge and active mode. The compact aluminium/plastic front housing combines low weight with robust build quality, and the pair includes USB rechargeable batteries for convenient charging without disposable cells. Multiple modes let you prioritize either extended battery life or maximum brightness.

How to use

Attach the front Aura 80 and the Nugget II rear light to the handlebars and seatpost or rack using the provided mounts or compatible silicone brackets. Charge both units via the integrated USB ports until the charge indicator shows full; a full recharge requires about 4.5 hours. Use the mode button on the front unit to cycle through the four light modes and check the top LEDs for remaining battery. Select higher-power mode for dark roads and boost situations, or Eco mode for extended runtime. The rear light is operated via its push button to choose steady or flashing output.

Recommendations

For reliable visibility, keep both front and rear lights charged before each ride. Use Eco or medium modes for everyday commuting to maximize battery life and reserve boost mode for poorly lit or high-speed conditions. Regularly clean the lens and check mounting tightness to ensure correct beam alignment and prevent accidental detachment.
