I have the lights now, there is a front and rear light.

Initial impressions.
The mount(s) were the main reason I bought this particular set of lights. The mounts looked sturdier than many of the “quick/easy” mounts I have seen. The handlebar mount does have a large rubber clamp that fits around my carbon bar, unfortunately the clamp only fits on the 22mm sections of the bar. My current carbon riser bar has a larger 31mm section in the center that it does not fit around. Not sure if a longer SS screw will fix this, yet. I am thinking about ordering a shorter plain flat bar which has a narrower 31mm section though, as I am a little crowded on my current, cut down, to 680mm riser bar. The front light also comes with a helmet mount. The top part of the helmet mount, that came in the kit, actually fits in the base of my helmets “camera” mount. Will experiment with helmet mounting both lights as I am aware there are some advantages to this mounting system.

The other thing I liked is the front light puts out 700 lumens, and has a flashing/strobe mode that saves the battery, as does the rear light. I plan to use both in the flashing mode on most rides, as the gravel roads I ride are in deep woods. With all the switch backs cars can appear quickly and I want to be seen. The lack of traffic sometimes means drivers may wander over to the wrong side of the very narrow roads.

Both lights charged up quickly with their Mini USB chargers. The caps over the Mini USB holes do not look like they will last, which may mean they will not be waterproof for long. This is typical of the caps on these USB charging ports though. The front light is better than the rear light, which is held on with a large rubber band. I knew this before I ordered the lights though. If the rear light does not want to stay in place I can always order a rear light with a better mounting system.
