The Lowdown: Knog Blinder ARC 640
Knog is more of a commuter light company, but this Blinder ARC 640 is their most powerful light and good enough for trail riding. Put one on the helmet or one on the bar and helmet and you're good to go.
Our key observation is that these lights were designed with quality and style. These lights have the look and feel of an Apple product, as rubber and metal are molded together to create a very slick device. A metal front for heat dissipation is integrated with a rubberized back for good grip and ergonomics.
