ROCKBROS Bike Tail Light, Smart Bicycle Tail Light with Brake Sensing, Waterproof Rear Bike Light, USB Rechargeable Bike Lights, Bike Lights for Night Riding

Our new upgraded bike tail light has two modes, normal and smart, with seven different lights in both modes. You can choose the right light mode according to the road conditions, which serves as a reminder and warning to oncoming vehicles. Whether it's day or night, the tail light light is clearly visible, greatly improving the safety of riding. Under the smart mode, the tail light will automatically sleep and wake up, saving more power than the normal mode. When braking, the tail light will automatically sense and continue to highlight 2S to remind the car behind.
