Sigma Aura 80/Nugget II

Debut of 2025 in the Sigma product line is a mid-budget set of front and rear lights for a bicycle. The set includes the Aura 80 headlight and Nugget II taillight: both accessories feature a plastic housing with water protection standard IPX4, are powered by built-in batteries, and have charge indicators (5-level and 2-level, respectively). They charge via a Micro-USB port, allowing connection to a power bank in the field.

Additionally, these products are distinguished by easy installation on the bicycle — using quick-release flexible mounts. The Sigma Aura 80/Nugget II set also offers compact sizes and a total weight of less than 150 grams. The included headlight has a range of 90 meters, plus additional side visibility provided by a pair of auxiliary Light Guide diodes. Users are offered 4 modes with different light outputs (brightness varies from 20 to 80 lux in increments of 20). The autonomy of the front light ranges from 4 hours at maximum brightness to 15 hours in eco mode. The taillight features increased lighting distance, up to 400 meters, has wide lighting angles of 220 degrees, and should operate up to 6 hours without recharging.
