The Strip Alert Drive Pro is an advanced LED bike taillight with our custom-programmed “Alert” technology. It features our Wide Angle Optics lens that provides up to 270° of visibility and our custom-programmed “Alert” technology. When decelerating, the light will turn solid, increase in output, 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. Its co-molded construction is super compact, highly water-resistant, and boasts five LEDs offering up to 300 lumens of output. With 5 output modes, including a Daytime Flash mode, it’s got options for any time of day or night. A versatile mounting system attaches to aero or round posts and it’s micro-USB rechargeable. This is the ultimate cycling taillight for impressive daytime visibility and superior visibility after dark.
