CatEye Rapid X2 Rear Safety Light

CatEye's Rapid X2 is a tiny, lightweight, all weather rear light for nighttime visibility. Its 50-lumen high-power LED lasts for up to 30 hours, features six modes, and automatically switches to flashing when you're at 20% power to provide an additional hour of light. A USB charger lets you refresh the rechargeable battery in two hours. You'll love the Rapid's side visibility when you're riding and its easy installation and removal when it needs recharged.
