The battery LED light set features a switchable brightness of 30 to 15 Lux. This dual adjustable brightness allows for optimal adaptation to environmental conditions, e.g., 10 Lux for well-lit streets and 20 Lux for poorly lit streets. Thanks to state-of-the-art LED technology, the battery life is up to 9 times longer than that of conventional light sources (compared to lights with traditional incandescent bulbs). The set includes a handlebar mount with quick attachment - rubber strips are provided for use with smaller handlebar diameters. The LED lifespan is up to 50,000 hours. This set is approved for all bicycles in accordance with the German Road Traffic Licensing Regulations (StVZO). The batteries are not rechargeable.
