Finding the best way to see and be seen in low light or nighttime conditions without dragging a giant headlight along for the ride can be a challenging search for many cyclists. You want lots of light in a small, lightweight, unobtrusive package. The NiteRider Pro 1400 Race Light delivers all that functionality in a breeze with 1400 lumens of light that perch sprightly on your helmet or handlebars to illuminate road and trail adventures without bulk. The NiteRider Pro 1400 Race Light is powered by a rechargeable 4 Cell Li Ion battery with beefy run times ranging from two hours on the steady, 1,400 lumen setting all the way up to 32. 75 hours on the flashing setting. With a total of five steady beam options and three flashing options between those two bookends, you can customize the brightness to meet your riding needs on the fly.
