Sigma Aura 100/Blaze Link (SD17950)

The Sigma bike light set is an accessory in the advanced price category, suitable for both daily use and long-distance road rides. A key feature of the set is its Bluetooth connectivity, simplifying the control process by allowing interaction with two devices from the front light: you can turn on both devices simultaneously and monitor their battery levels through indicators located nearby.

The Sigma Aura 100/Blaze Link set supports smart lighting: a built-in brightness sensor enables automatic operation without user intervention (when it gets dark outside) and even adjusts the optimal lighting output from 25 to 100 lux. The front bike light is based on an Osram diode and supports 5 modes: fully automatic and four constant lighting options with varying brightness (with a maximum range of 110 meters).

It also features side light guides to enhance the visibility of your vehicle. The tail light has two modes (excluding Auto) — constant illumination and intermittent flashes. Both accessories are powered by rechargeable batteries and charged via a microUSB port. The front light's battery life ranges from 3 to 12 hours, while the tail light lasts up to 5 hours. Other notable features of the set include readiness for various weather conditions (IPX4 water resistance), easy installation with flexible quick-release mounts, and a relatively lightweight total weight (approximately 130 grams).
