CygoliteDart 210 USB Bicycle Light

This is a very compact but bright Daytime bike light. I use it exclusively in the daytime blinking mode. It attaches easily to my handlebars, and a single charge lasts about 10 hours, enough for at least a couple of long rides.Charging is via micro USB, just be careful to properly orient the tiny micro plug end and be gentle when engaging it.The rubber attachment strap is very easy to use, I put a single layer of friction tape on my bar where the light is attached, and the light never moves once secured by the strap.I used this light on every ride through the 2017 season, never any issues in over 5k miles of riding.Highly recommended.6/2019 Update: Still going strong, used on every ride for the past 12k miles, working perfectly, no noticeable deterioration in battery life or light output.

I use this light on flashing setting as a daytime running light. For that purpose it seems adequately powerful, and has a runtime sufficient to accommodate my longest rides. It is also very light and compact and attaches easily and quickly to my handlebars without any additional hardware. The one downside: I find the button controls to be less than intuitive and fumble with them every time I turn the light on or off.

I've put this light through everything for 3 years. Mtb in the mud and rain. Work nights in the garage. Camping. Hiking. Very reliable and long lasting. Not super bright, like my 1500 lumen light, but certainly bright enough to get you around your local area and home on a ride that runs late. And very light weight... don't think twice about bringing it along "just in case." I'm buying my 3rd one now (2nd for a friend, 3rd for my son).

An ideal tiny light to be used as a daylight visible flashing front light in cities and/or wherever there is a lot of traffic that can dart in and out of lanes. Excellent design, material and build quality. For nighttime use, should be combined with a more powerful light and used in its flashing nighttime mode.

The media could not be loaded.  Great daytime supplement to the Supernova M99 Pure that is my primary day and night headlight powered by my bike's internal battery. Charges last a very long time in the DayLightning mode that I always use when I ride - I think I get at least 10 hours from it. Many adjustable light modes - sure to find the best fit for your needs. Mounts securely to my handlebar, and requires minimum maintenance and care. I can't imagine a daytime front light to get you seen by car and bike traffic and pedestrians more effectively with less bother.

Very bright, small and convenient. The strobe feature is great for NYC.

I already have one, bought this for a friend cause its a good working and simple bike light....

Bought as a backup to a much larger Cygolight light and to be used as a daytime running light in flash mode.Easy to attach and detach.Often I loan it out to people in my bike group with uncharged or unworking headlights.

Exactly what you want from a white forward facing light. Attaches easily to the handle bars. Charges via a USB so no more running out of tiny batteries. Can be seen in daylight. All good.
