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 NiteRiderâ€™s custom engineered optics for a balanced long-throw and wide flood beam pattern. New OLED display shows detailed information about mode and battery life. Stay safe when on the road day or night with the Solas. Two steady modes, two flash modes and a group ride mode to avoid blinding your riding partners. An easy on/off seatpost strap mount makes it easy to move this light from bike to bike.
