Ravemen TR400 Taillight is backordered and will ship as soon as it is back in stock.
The Ravemen TR400 is a high-visibility rear light for road cyclists, commuters and endurance riders who want automatic safety functions rather than relying entirely on manual mode changes. Its wide rear viewing angle improves visibility from approaching traffic, while dedicated daytime and night behaviours make it useful across changing light conditions. Two supplied mounting systems also let riders choose between a conventional seatpost position and a cleaner saddle-rail installation.
Adapts while Riding. A built-in light sensor automatically changes between Daytime Flash and Breathing Mode according to ambient light. Brake detection increases visibility when deceleration is detected, while automatic power management switches the light off after a period without movement and restarts it when vibration returns. Mode memory retains the previously selected setting, reducing the need to configure the light again before each ride.
Practical for Daily Use. The hidden USB-C charging port keeps the charging interface protected during riding, while a built-in battery indicator lets the rider check remaining charge directly from the light. The supplied seatpost and saddle-rail mounts give the TR400 flexibility across different bike setups, making it suitable for riders who want one rear light that can move between road, gravel and commuter bikes.
