CatEye AMPP400

At 400 lumens, this light is best suited for urban commuting and well-lit paths. While it offers good visibility for drivers to see you, it may not provide enough throw for high-speed riding on completely dark, unlit trails.

Battery life varies by mode. You can expect roughly 2 hours on the high setting, while the daytime and flashing modes will last significantly longer. The low battery indicator will turn red when you have about 20% power remaining.

Yes, the AMPP400 has an IPX4 water-resistance rating. This means it is protected against splashing water from any angle, making it perfectly safe to use during standard rainy commutes.

Yes, it includes the CatEye FlexTight bracket, which is a tool-free, adjustable mount that fits most standard handlebar diameters. It is designed for quick attachment and removal.

The light charges via a standard USB port. A full charge takes approximately 4.5 hours, and because it uses a lithium-ion battery, you do not need to worry about replacing disposable cells.

The included bracket is designed for handlebars, but the AMPP400 is compatible with optional CatEye helmet mounts. You would need to purchase that specific accessory separately to attach it to your helmet.
