Powerful and weatherproof: Equipped with a magnet, this rear light docks onto the HERITAGE 2.0 bike helmet from our range. 50 lumens guarantee good visibility, even when riding in the twilight. There are 3 different light modes available: In continuous light mode, the rear light remains on for 5 hours, in flashing light mode for 10 hours and in eco-pulse mode for up to 12 hours. The charging process then takes 2 hours using the USB-C cable supplied. Rain and splash water cannot harm the high-quality light. The light contains LED lamps. Protection class IP54. Note: The LED lighting is not STVZO-approved and therefore does not replace a STVZO-compliant lighting system on your bike and is not a supplement in terms of the STVZO. Use of the light is at your own risk and responsibility.
