With 2 LEDs pumping out 65 lumens of power, 270 degrees of visibility and our unique BLITZ Daytime Running Mode the Dayblazer 65 is focused on safety, so you can focus on your ride. Also, because of the narrow profile of our unique mounting bracket, the Dayblazer 65 tail light can be mounted to just about anything you can think of from round or aero seat posts, to seat stays, to a rear rack, or your back pack.
