The Dayblazer 400 and Click USB Light Combo is the younger sibling to the series, but it still puts out a powerful amount of light--and comes at an almost unbelievable cost. 400 lumens brighten the way forward, while the Click USB Light makes your position obvious to passing cars, and has excellent side visibility to make intersections a safer experience. This simple light has a single-touch operation that is easy to use even while riding, but cycles through four different modes depending on your needs. The Dayblazer 400 features BLITZ daytime running mode, which is designed to help you be seen even in the bright afternoon sun. Both lights feature an LED fuel gauge which changes color as battery levels change, so you can tell how much charge is contained with a single glance. They're water-resistant, durable, and install quickly without any tools so you can switch them from bike to bike without a hassle.
