Cateye AMPP400S

The 400-lumen output is ideal for urban commuting and well-lit bike paths, providing enough visibility to see and be seen. If you frequently ride on unlit trails or pitch-black roads, you may want a higher-lumen light for better distance projection.

The light automatically saves the last mode you used before turning it off. When you power it back on, it will return to that specific setting, saving you from cycling through the modes every time you start your ride.

Yes, the AMPP400S features a dedicated daylight-visible flash mode. This pattern is specifically designed to grab the attention of drivers and other road users in bright, high-traffic conditions.

The light uses a standard handlebar mount designed to fit most common bicycle handlebar diameters. It is straightforward to install and remove without needing any tools.

The unit includes a built-in battery indicator light. When the light turns red, it signals that you have a limited amount of runtime remaining, giving you enough time to finish your ride or reach a charging point.

Yes, the lens is engineered to cast light to the sides, which helps increase your peripheral awareness. This is particularly useful at intersections where you need to be visible to cross-traffic.
