Highly Visible With The Highest Quality

Stay safe during all times of day with a bike light that lights up the road. The Lezyne Zecto Alert Drive is a compact, innovative rear LED bike light. Featuring smart custom-programmed "Alert" technology, which truly allows you to be seen wherever you ride. 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 you resume your ride.

This fantastic rear bike light is 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. Low battery? No problem! The Zecto Alert includes a micro-USB cable for easy recharge. Additional features include side visibility and a replaceable mounting strap.

    Lezyne Zecto Alert Drive Rear Light

    I have very strongly mixed views regarding this tail light. I like the basic concept itself. However, there are many flaws regarding it's functionality. I have several bikes. One of them has an aero style seat post that the tail light does not work on at all. The charge port cover for water proofing does not fit well, so it doesn't completely keep out water. It is impossible to distinguish which luminosity output setting the light is at, so you don't know if the current charge will last for 2 hours or 15 hours. I don't believe the fully charged light's runtime will last 15 hours on any of the settings. The alert seems to be erratic. But if you can look past all of these details which are bothersome to me, then it's an otherwise good light.

    Alert Drive Rear Light a Fine Product

    Ordered 2,for my and my wife's bicycles to increase visibility and have a stop light feature. Very visible and bright with different flash modes, well made, and the stop light feature works well and is helpful to the rider behind the front rider as well as to vehicles. Glad to have it for all roads shared with traffic...
