Projecting a whooping 450 lumens of brilliant light, the NiteRider Lumina Micro 450 Headlight helps you safely navigate every ride, allowing you to see and be seen. The bright LED has four light modes, plus a Daylight Flash mode that provide 1:30 - 4:00 hours of steady light and up to 14 hours of blinking light. It's USB rechargeable in 3:30 hours and when used with Intellicharge, it recharges in only 1:45 hours. Low battery indicator changes from blue to red, letting you know when power is low and handlebar strap mount with quick-release tab allows easy-on, easy-off. Compact, lightweight design is perfect for helmet mounting (helmet mount not included).
