The light automatically turns off after 30 seconds of inactivity and turns back on when motion is detected (except in steady mode). Built-in ambient light sensor saves power by adjusting brightness intelligently. -

Easy Dual-Mount Installation for Versatile Fit
ROCKBROS tail light offers two secure mounting methods to match your bike setup:
Under-Saddle Rail Mount: Simply unscrew the bracket, fix it onto the saddle rails, and tighten the screws for a firm hold. Then twist the tail light clockwise into the bracket until it locks securely. Ideal for a clean, low-profile look.
Seatpost Mount: Find the right position on your seatpost, wrap the durable silicone strap around it, and secure the tail light by twisting it clockwise into the base. This tool-free option is fast and easy—perfect for everyday use or switching between bikes.Both mounting styles ensure a stable fit and quick installation without compromising on safety or performance.
