NiteRider's MiNewt Mini.300-USB is a powerful compact light that puts out an impressive 125-300 lumens for up to five hours! And it's light, too, weighing in at a feathery 175 grams! Attachment is easy on any handlebar and three brightness levels let you customize the output to your speed. Recharging is easy—just plug it into the wall or your computer's USB port. And so you don't get caught in the dark, the battery indicator switches from green to red when power is low.
