A powerful one piece light capable of handling everything from mountain bike rides to daily commutes. New Boost mode allows the light to run at its absolute maximum, pushing every lumen through NiteRider’s custom engineered optics for a balanced long-throw and wide flood beam pattern. The Sabre is a super bright, light weight USB rechargeable LED taillight. It utilizes a multi LED array designed for eye catching visibility in both day and night. With the addition of amber colored side lights, the Sabre provides 180 degrees of protection.
