Cycling in low light conditions can be a risky proposition. While it's not always our first choice, sometimes duty calls. Whether you're commuting to appointments or fitting in your daily training ride when time allows, the Lezyne Zecto Drive Auto Light is a low weight, unobtrusive, easily stowed beacon of cycling safety. The Zecto Drive Auto Light boasts three LEDs that produce between five and 15 lumens, depending on which of the six settings you're using. These include daytime flash, which is a bright, 20 lumen flash for use during daytime cycling, three flashing modes at 10 lumens that last from four to seven and a half hours, an economy mode that provides five lumens for just over five hours, and a blast mode that produces 10 lumens for three hours and 30 minutes. The inclusion of Lezyne's Intelligent Power Indicator ensures that the light will never unexpectedly die on the road, because red, green, and blue LEDs visible from the side tell you precisely the light's level of charge during use and while charging. The light's body features durable aluminum construction and parts that are precisely CNC machined, is water resistant so you can use it in the rain with relative impunity, and it includes a clip to mount it on straps or clothing. You can also mount it onto your seatpost with provided silicone strap. On top of all this, the Zecto Drive Auto has a motion detecting sensor built into it. When it stops registering movement for three minutes, it shuts itself off. You'll save juice at long stoplights and you'll also never have to worry about uselessly running through your batteries because you forgot to turn it off while your bike's locked up. The Lezyne Zecto Drive Auto Light kicks back on as soon as motion is resumed.
