Bright Urban Headlight for Daily Commutes
The Kryptonite Alley F-650 is a compact front headlight that puts out a powerful 650-lumen beam, giving you enough light for dark paths while staying practical for city streets and commuting. Six modes cover everything from fully dark rides to daytime pulse, so you can tune brightness and battery life to your route.
Side illumination ports help you stand out at intersections, while a built-in battery indicator and power-saving mode take the guesswork out of charging. USB recharging and a simple handlebar mount keep setup easy, so the light can live on your bike and just do its job.
