The Nite Ize® WrapLit is two clever devices in one. We've securely attached the tough INOVA® Microlight to our durable, flexible 18 Gear Tie™, creating a whole new category of versatility and usefulness. Encased in durable polycarbonate plastic housing, the battery-powered Microlight has four functions (high power, low power, strobe, and signal). Its focused, bright white LED has an effective range of up to 50 feet and one-mile visibility. The Gear Tie, with its strong, bendable wire interior and sturdy rubber exterior, can be configured and reconfigured at either end, so you can position the light from almost any angle imaginable. Loop to hang, twist to attach, bend to prop—even wear the Gear Tie around your neck for hands-free illumination, precisely where you need it.
