Cateye AMPP 400S II/Viz100 II Bike Light Set: USB-C

The AMPP400S / ViZ100 II set pairs a 400-lumen rechargeable front light with a 100-lumen rear light. The AMPP400S uses an OptiCube™ lens to produce a wide beam and provides side visibility. Its adjustable FlexTight™ bracket holds the light on the handlebar.

The compact ViZ100 II uses a focused lens for rear and side visibility, with Daytime HyperFlash modes for riding in daylight. Both lights recharge by USB-C, and the rear light has a replaceable battery. The set is advertised with a five-year warranty in the UK.
