The BEATLEDZ SG-3 lights are characterized by their rechargeability. The charging cable is included. With the BEATLEDZ SG-3, you, your dog or horse are clearly visible in the dark, so that road users can adjust their speed early. In traffic, "obstacles" such as dogs or horses are marked in yellow, while vehicles always have a white and red light. That's why the yellow light is always our recommendation to make the dog clearly visible in traffic.
