NiteRider's Lumina Flare is a perfect all-in-one light solution. With 650 lumens of white light up front and 1 watt of red in the rear, you get the brightness of a powerful headlight combined with the safety and visibility of a taillight. And at just 177 grams, you won't even notice it's there! Attachment is easy, too, on handlebars up to 31.8mm in diameter or on top of your helmet. There are five modes to choose from: high, medium, low, energy-saving walk, and flash. Plus, you can charge it off a computer's USB port!
