The Zecto Alert Drive is a compact, innovative rear LED bike light featuring a Daytime Flash mode and our custom programmed “Alert” technology. When decelerating, the light will turn solid like a brake light and then provide a distinct flash pattern once stopped to alert riders or vehicles from behind. The light will then change back to its previous output mode once the rider resumes his or her ride. It’s constructed from lightweight, durable Composite Matrix and features a stylish machined aluminum bezel. Its patented 2-in-1 clip/strap system is highly versatile allowing it to strap to posts or clip on a bag. The light has a max output of 80 lumens, five different output modes and a battery runtime of up to 15 hours—and includes a micro-USB cable. Additional features include side visibility and a replaceable mounting strap.
