The Zecto Drive 250+ Front is a compact, high-visibility bike light with six bright LEDs providing up to 250 lumens. It has six modes (solid and flashing), including a Daytime Flash for increased visibility. A Power Indicator shows battery life and improves side visibility. It attaches easily to handlebars with a clip or strap. It's IPX7 waterproof, meaning it can handle harsh weather. With a 650 mAh battery, it can run up to 40 hours on its lowest setting. It charges via waterproof USB-C (cable not included). The Lezyne Infinite Power Pack+ can extend its runtime, but the original Power Pack isn't compatible. USB-C cable not included.
