Product details

The AURA 45 USB bicycle light from SIGMA SPORT offers 45 lux and a harmonious light distribution up to a distance of approximately 55 meters. Safety-conscious riders benefit from the integrated brightness sensor, which automatically adjusts the light intensity to ensure the longest possible burn time. This bicycle lamp is ideal for city riders who also travel off well-lit roads.

Rechargeable
The AURA 45 USB features a built-in battery that can be charged via the micro-USB port, even at any PC. With the included micro-USB cable, the front light can be fully recharged in a maximum of 2.8 hours. The lithium-ion battery provides deep discharge and overcharge protection, has no memory effect, and can be easily recharged to full capacity.

Side visibility
Wide side light elements enhance visibility.
