Traffic light inspiration – modern look
Red, yellow, and green colors attract attention. Vertical mounting reduces air resistance and improves visibility.

5 lighting modes – easy switching
Change modes with a single button. Double-click to switch between intelligent and manual modes – adapt the light to different driving scenarios.

Smart braking – all three colors light up simultaneously
The built-in sensor immediately detects braking and turns on the red, yellow and green lights for approximately 3 seconds – effectively warning vehicles behind.

Light sensor - energy saving
It automatically activates the light in dark conditions, such as in a tunnel or at night. During the day, it goes into sleep mode when not in use.

Built-in battery – fast charging via USB-C
A red flashing light indicates charging, and a green flashing light indicates full charge. Charging time is approximately 1.5 hours.

IP64 waterproof – rain-ready
Splash-proof, perfect for rainy weather (do not immerse in water).

The set includes brackets for mounting on the seat post or seat rails – adjust to your bike.
