SIGMA Aura 40 USB-C Front Light

The SIGMA Aura 40 is a reliable daily companion for urban cycling, featuring an improved light pattern with a 50-metre beam range. Its integrated rechargeable battery provides up to 9 hours of runtime in High mode and an impressive 29 hours in Eco mode, with a full recharge via USB-C taking just 3 hours.

Tool-free mounting is effortless thanks to the 360° adjustable silicone bracket with a quick-release function, while the side Light Guide enhances lateral visibility for added safety. The double-click activation prevents accidental switch-on, and a short button press reveals the battery status on the 3-stage LED indicator.
