Author XYRIUS Brake USB Rear Light 400 lm Black with Red Lens

Most rear lights simply glow—the XYRIUS Brake actively reacts. Its integrated accelerometer detects deceleration and instantly boosts output to 400 lumens, giving drivers behind you a clear, urgent signal. A high-power COB LED, 270° beam, and rugged IPX4 build make it a standout choice for commuters and road riders who demand more than passive visibility.

Highlights

• 400-lumen high-power COB LED for excellent visibility
• Automatic brake light via integrated accelerometer
• USB-C rechargeable 500 mAh battery
• Tool-free silicone strap fits seatposts 22–35 mm
• IPX4 water resistance for all-weather riding

In daily use

Mounting takes seconds with the stretchy silicone strap—no tools, no brackets. It fits round and aero seatposts and leaves room for saddle bags. The USB-C port charges in about 2 hours, and status LEDs show battery level and charging progress. Choose from steady, flash, pulse, or brake modes; runtime reaches up to 20 hours in lower modes, so you can ride for days between charges.
