The Lezyne Zecto² Drive Max 400 is a rear bicycle light with a maximum output of 400 lumens. A daytime flash mode gives it presence in bright sun, when a steady beam is easy to miss. Wide angle optics spread the output across roughly 270 degrees, so the light remains visible to traffic approaching from the side as well as from behind.
Runtime reaches up to 100 hours, drawn from a 1300 mAh battery the rider can replace rather than retire the light. Charging is over a water resistant USB-C port, and the composite body carries an IPX7 waterproof rating. The strap mount fits round, aero and D-shaped seatposts, and the light also works with most quarter-turn mounts.
