2015 Lights Shootout

Lezyne Zecto

The Lezyne Zecto Auto dazzles with an entertaining array of flash modes. It's got good rear visibility as well as side visibility and it has such a small form factor that you can just leave it mounted on your bike permanently.

It's rechargeable and it delivers up to 2 hours on solid 'high' mode, so flashing mode is quite a bit longer than that. The switch and the charging port are neatly integrated at the top and bottom of the light.

But the best thing about the light is it has a 'sleep' mode that is awakened by movement and put to sleep by inactivity. Thus, it is an automatic light that turns itself on and off. This is a huge idea since many users forget to turn their light on or off, so they're either compromising safety or battery life. But with a light that turns on and off by itself, we should be covered right?

In sleep mode, the light turns on at the slightest bit of movement. After 2 minutes of no motion, it will turn itself off. The only downside is it will drain a tiny bit of battery charge while in sleep mode.

This light has a front light sibling as well, so everything we've said about the tail light applies to a 'to be seen' front light version.

Overall Rating

5 Stars
5 out of 5 Stars

It's a great light that has good visibility in a very small package. The fact that it can automatically turn itself on and off makes it a sure winner.
