NiteRider's Lumina Micro 250/Solas Combo comes in a tiny package but puts out a huge amount of light that will cover you both front and rear. The Micro delivers up to 250 lumens, lasts up to 14 hours, and weighs in at only 130 grams! Plus, it installs quickly on your handlebars. You'll remain visible throughout your travels with one of the four modes: high, medium, low, and energy-saving walk. An indicator light comes on when the battery is low so you know to recharge with a computer-friendly USB cord. And, should you throw it in a bag for later use, the Micro's lock-out mode ensures it won't accidentally turn on and waste battery life. And, this combo features the Solas, which boasts a 2-watt LED, produces 30 lumens, and has 4 settings including a daylight safety flash mode to keep you visible to others.
