Both front and rear lights are durable and visible in pre dawn rides. I use the rear light at all times of day and it remembers my last light pattern. Both charge quickly and last
Got this set of lights after doing some decent research on a few other brands. I ended up going with Lezyne because of the various light settings and because the battery life to lumen output ratio was right for the riding I do. I now enjoy that I can be seen in the day just as much as I can be seen at night.
