Our latest to-see-by headlight the Flash 500 brings Flux-style beam control to a more budget-friendly pricepoint. The Flash headlight combines a clean compact design with a simple-yet-elegant silicone strap that reminds us of a watchband design from our friends in Cupertino. With two different-sized straps included you can dial in just the right amount of stretch to keep the Flash secure while ensuring super fast install and removal. Now you see it now you don't.
