The Sigma Aura 40 is a compact, powerful front light designed for urban traffic, providing optimal visibility with up to 40 Lux and a range of 50 meters. With two lighting modes – High for full power and Eco for extended runtime – it adapts flexibly to any riding situation. The integrated battery can be charged via USB-C in just three hours, allowing for eco-friendly riding and long-term cost savings. Side LEDs enhance visibility, while the splash-proof housing rated at IP44 ensures reliable performance even in bad weather. Installation is tool-free with a 360° mount, and the quick-release feature allows for easy removal of the light. A three-stage battery indicator keeps you informed about the battery status, and the smart on/off function prevents accidental activation. With its sustainable design and replaceable battery, the Aura 40 meets all requirements of the EU Battery Directive, combining safety, comfort, and sustainability in a modern design.
