The Exposure Link DayBright Mk4 Front Bike Light is a lightweight, high-visibility daytime running bike light designed to keep you seen and safe on busy city streets. Compact yet powerful, the Link DayBright Mk4 delivers exceptional brightness and visibility in all lighting conditions, making it an essential safety upgrade for urban commuting, road cycling, and daytime riding.

Engineered for maximum awareness, the Link DayBright Mk4 features Exposure’s signature DayBright Pulse Pattern, which cuts through visual clutter, traffic and changing light conditions far more effectively than a standard constant beam. When mounted high on a helmet or handlebars, the light remains clearly visible above cars and obstacles, dramatically improving rider visibility in traffic.

With 360-degree visibility from a single unit, this front bike light ensures you are seen from all angles, helping motorists and other road users spot you sooner. The lightweight construction makes it ideal for helmet mounting without compromising comfort, while the USB-C rechargeable battery offers fast, convenient charging for everyday use.

Perfect for commuters, road cyclists and anyone riding in high-traffic environments, the Exposure Link DayBright Mk4 is a proven solution for improving daytime safety and confidence on the road.
