When the sun goes down and you"re rushing across town to a friends house, the NiteRider Mako 200 Light will light the way for safe passage. Unlike most entry-level lights that"re just bright enough to make the overly-cautious motorist aware of your presence, the Mako 200 light illuminates a visible path while adding to your safety. Using a Cree LED bulb, the Mako 200 light broadcasts a wide, 200 lumen beam across the road so you can avoid hitting fallen branches at full speed. With two steady light settings and a strobe setting, it"s a breeze to dial in the best output level for your ride. And since lateral visibility is just as important as frontal visibility, NiteRider installed "gills" on both sides of the light body to emit red light on every setting. The Mako also comes equipped with a handlebar mount that can accommodate bars up to 31. 8mm in diameter. The NiteRider Mako 200 Light comes with two AA batteries and weighs approximately 165g.
