Some lights project their output into one specific area, illuminating everything within that space with exceptional detail, but that’s frequently at the expense of broader coverage. It’s powerful enough for most black-graded trail centre runs and the beam’s white hue with brown/red highlights illuminates trail surfaces well adding good depth. As its looks suggest, the main selling point of the Knog Cobber Mid rear light is side-on visibility, and it certainly doesn't disappoint in this regard.Probably made in China like the rest of them, unless it's one of these or similar BT-70791CK, BB-2590/U 7. With a versatile clip mount for straps or tubes, plus a robust construction, the ZDM is a bikepacking winner.

High and low beams have different patterns, with the high beam focusing light in the distance and the low beam flooding the closer area.
