LIGHT CATEYE TL-AU630

The Cateye TL-AU630 (Rapid 3 Auto) is a dependable rear light built for riders who want set-and-forget convenience, strong visibility, and long battery life. Designed by CatEye, it combines simple operation with smart features that make everyday riding safer.

A standout feature is its automatic sensor system, which turns the light on when it detects darkness and motion, and keeps it illuminated for a short period when you stop—perfect for traffic lights and commuting situations.

The light uses a 3-LED setup (including a high-power centre LED) with OptiCube™ lens technology, delivering strong, attention-grabbing visibility from the rear.

Powered by a single AA battery, it offers excellent runtime—up to 80 hours in flashing mode, making it a practical choice for riders who prefer long-lasting, replaceable batteries over rechargeable units.
