Ravemen TR400 USB Rechargeable Rear Light

The Ravemen TR400 USB Rechargeable Rear Light is a powerful smart safety light designed to maximize rider visibility in both daytime and nighttime conditions. Producing up to 400 lumens of ultra-bright output, the TR400 can be seen from distances of up to 2.6km, while its 270° wide-angle beam ensures approaching motorists and other road users can spot you from multiple directions for enhanced road safety.

Equipped with an intelligent light sensor, the TR400 automatically adjusts its lighting mode based on surrounding brightness, switching seamlessly between a highly visible Daytime Flash mode and a gentle Breathing mode at night. The integrated brake detection sensor further enhances safety by automatically increasing brightness for three seconds when braking, providing a clear warning signal to riders and vehicles behind you.

Designed for everyday convenience, the TR400 features an automatic power on/off function that turns the light off after two minutes of inactivity and automatically powers it back on when motion is detected. A built-in battery level indicator allows you to quickly check remaining battery life, while the concealed USB-C charging port keeps the design clean and well protected from dirt and moisture.

Powered by a high-capacity 2000mAh rechargeable lithium-polymer battery, the TR400 delivers an impressive runtime of up to 350 hours, making it ideal for commuting, road cycling, gravel riding, and endurance adventures. With its IPX6 waterproof rating and versatile mounting options for both seatposts and saddle rails, the TR400 is built to perform reliably in all weather conditions.
