Headlights

Serfas' Thunderbolt Headlight delivers 90 lumens in an extremely versatile, USB-rechargeable package. Attach the water-resistant silicone body nearly anywhere on your bike, and use the high, low, or two flash modes to make sure cars, cyclists and pedestrians can see you at night. At just 50 grams, you won't even notice it's on your bike — but others will!

CatEye's Rapid X2 is a tiny, lightweight, all weather front light for nighttime safety. Its high-power 100-lumen LED lasts for up to 30 hours, features six modes, and automatically switches to flashing when you're at 20% battery power to provide an additional hour of light. A USB charger lets you refresh the rechargeable battery in two hours.
