The TR500 from Ravemen is the absolute most powerful rear light Ravemen has made so far.

Fantastic visibility both at night and during the day.

The compact rear light can deliver up to 500 Lumen with its 3 CREE Diodes in warning flash mode, which is so powerful that it should ideally only be used during the day.

A strong battery can keep the rear light running for up to 21 hours, depending on temperature and light mode.

The light comes with equipment so it can be mounted on round seatposts or aero seatposts.

The compact aerodynamic design, powerful battery, and incredible light output make this rear light one of the best rear lights available for road cycling.
