Femto Drive is a compact, bright, safety light. Lens is made of high-grade optical material and serves as an activation button that cycles through four flash and one solid mode. CNC machined aluminum body makes the Femto Drive a durable and weather resistant light. Composite Matrix back plate can be unscrewed to replace the two CR2032 disposable batteries. Multi-position silicon rubber strap attaches directly to the back plate to secure the light to a wide range of handlebar and seat tube diameters.
