The NiteRider® Sentinel™ 250 is designed to increase cycling safety by way of 2 varying flash patterns and 2 steady beams (High/Group Ride Mode). Behind the durable red lens and casing are two powerful LEDs that emit 250 lumens in the brightest Daylight Visible Flash setting, allowing you to be seen day or night. For enhanced safety, the Laser Lane modes (3) are designed to project ultra-bright laser lines on the ground. This creates a virtual lane for the rider, further increasing visibility.
