The Lezyne Femto Drive Front is a compact, bright, safety light. The lens is made of high-grade optical material and serves as an activation button that cycles through four flash and one solid mode. The CNC machined aluminum body makes the Femto Drive a durable and weather resistant light. The Composite Matrix back plate can be unscrewed to replace the two CR2032 disposable batteries. The 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.
