Ravemen TR150 Tail Light

The TR150 uses an internal motion sensor to detect deceleration. When you slow down, the light automatically increases its output to 150 lumens, acting like a brake light on a car to alert drivers behind you.

Yes, it features an IPX6 water resistance rating. This means it is protected against powerful water jets, so it will handle heavy rain, mud, and road spray without issue.

It is quite reliable. The light uses a motion sensor to detect when your bike is stationary; if it doesn't sense movement for a set period, it will turn off to save battery and turn back on as soon as you start riding again.

The TR150 uses a flexible rubber strap mounting system. While it is designed to fit most standard round seatposts, the strap is versatile enough to accommodate many aero-shaped posts, though fit may vary depending on the specific profile.

The maximum runtime is 18.5 hours, though this depends heavily on the mode you choose. Using the brightest setting or constant flashing modes will drain the battery faster than the lower-intensity or energy-saving modes.

Yes, the USB-C port is standard and easily accessible on the unit. Because it uses USB-C, it charges relatively quickly compared to older micro-USB lights, making it convenient for daily commuters.
