Bontrager Ion

The Ion 120 is designed primarily as a 'be-seen' light for commuting and urban environments, not as a primary source for navigating dark, unlit trails. Its 120-lumen output is excellent for increasing your visibility to others, but you will likely need a more powerful light if you plan to ride on pitch-black paths.

No, the Ion 120 is powered by three AAA batteries. While this means you will need to replace them periodically, it allows you to swap in fresh batteries instantly on long rides without waiting for a recharge.

The included quick-release bracket is designed specifically for handlebar mounting. It is not intended for helmet attachment, though it is compatible with Bontrager's Blendr integrated mounting ecosystem if you have a compatible stem or mount.

The Ion 120 is not rated as waterproof. It can handle light mist or a light sprinkle, but it is not designed to be submerged or used in heavy, sustained downpours.

The light housing is shaped to allow the LED beam to wrap around the sides of the unit. This provides a wider field of illumination, making you more visible to traffic approaching from intersections or side streets.
