ROCKBROS Traffic Tail Light

The light uses a built-in vibration sensor to detect deceleration. When you slow down, the sensor triggers all three integrated lights—red, yellow, and green—to shine brightly, alerting drivers behind you that you are braking.

It features an ambient light sensor that automatically activates the light in low-light conditions and puts it into sleep mode during the day to save battery. However, you will still need to manually power the unit on initially to enable these smart features.

Yes, the light has an IP64 waterproof rating, which means it is protected against splashing water from any angle. It is reliable for rainy commutes, though it should not be submerged in water.

The rechargeable battery provides up to 50 hours of runtime, depending on the lighting mode you select. It uses a standard USB-C interface for convenient and relatively quick recharging.

The light includes multiple mounting options designed to accommodate various bicycle setups, such as different seat post diameters. It is built to be versatile and straightforward to install on most standard frames.

The five modes allow you to adjust the light's intensity and pattern to match your environment, such as steady beams for dark roads or flashing patterns for increased visibility in traffic. You can cycle through these modes to find the best balance between battery life and visibility for your specific ride.
