SIGMA AURA 40 USB Front Light: Bright, Safe, and Reliable City Cycling

Illuminate your path and ride with confidence using the SIGMA AURA 40 USB, a premium front light designed for the safety-conscious urban cyclist and daily commuter. This powerful and compact light delivers exceptional performance, ensuring you can see and be seen in any traffic situation. Fully compliant with the stringent German StVZO regulations, the AURA 40 provides a powerful, focused beam without dazzling oncoming traffic, making it the perfect companion for navigating busy city streets and unlit bike paths.

Your Key Benefits for a Safer Ride

The AURA 40 is engineered to enhance your safety and convenience. Its core benefit lies in its perfectly crafted light pattern. With a powerful 40 lux output, it casts a bright, homogenous beam that illuminates the road up to 50 meters ahead, allowing you to spot potential hazards early and react in time. Unlike simple floodlights, the StVZO-approved lens focuses the light where you need it most—on the road ahead—while preventing upward glare that can blind drivers and other cyclists. Furthermore, the integrated "Light Guide" on the sides of the housing significantly increases your lateral visibility, a crucial safety feature for being noticed at intersections and junctions.

Packed with User-Friendly Features

SIGMA has designed the AURA 40 with the everyday rider in mind, focusing on simplicity and reliability.

* Two Versatile Light Modes: Easily switch between two modes to match your environment and conserve battery. The Standard mode provides the full 40 lux for maximum visibility, while the Eco mode offers a solid 20 lux, perfect for well-lit streets or extending your ride time.
* Convenient USB Recharging: Forget disposable batteries. The integrated lithium-ion battery is easily recharged via the included Micro-USB cable. This eco-friendly solution saves you money and is ready to go after a charge time of just 3.5 hours.
* Intelligent Battery Indicator: Never get caught in the dark unexpectedly. A two-stage battery indicator on the control button shows green when the capacity is above 70% and turns red when it drops below 30%, giving you ample warning to head home or switch to Eco mode. The indicator also provides status updates during the charging process.
* Tool-Free Mounting: The flexible silicone strap allows for quick and secure mounting on any handlebar with a diameter of 22 to 32 mm. You can attach or detach the light in seconds without any tools, making it easy to remove for charging or to prevent theft.
* All-Weather Durability: Don´t let a little rain stop you. The AURA 40 is protected against splashing water from all directions according to the IPX4 standard, ensuring reliable function even in wet conditions.
