Bike lights must be visible, flexible, durable, and moderately priced (because you will loose them, break them, etc). Therefore a good light needs to be bright and visible from moderate angles. It needs to be designed to mount on a variety of objects and adjust so that it point in the right direction, and stays pointed in that direction. And it must hold a charge for several hours and when not in use. That's it. It does not need to send morse code, be visible from miles away, or serve as a wifi hot spot. This bike light succeeds on these points!

Long lasting and visible, easy to use, adjust, and place in a variety of locations (seat, helmet, backpack).

Definitely a bright safety light. Bright enough to be seen from all angles, without being so bright that you are in danger of blinding fellow cyclists, pedestrians, or motorists.

Multiple options for installation. 4 different options. Light starts up in solid mode, press and hold for flashing strobe mode. 1 second press to turn off.
