Lupine Rotlicht is a well-known rear light. But now comes a new version - the Rotlicht Pro BT. With Bluetooth control and 120 lumen luminosity. The StVZO-compliant rear light uses 22 AMS OSRAM Synios LEDs to generate a 360-degree beam pattern for uniform illumination and visibility from all sides. A brake light sensor automatically increases the brightness when braking, while a brightness sensor automatically activates the light in the dark. The 55 gram CNC-machined aluminium housing is waterproof and impact-resistant.
