Nice little set of lights with good flash options. One thing to know about these lights. They are sometimes shipped with dead, dead, dead batteries. So dead that when you plug them in to charge for the first time, they may take about 10-15 minutes before the charge light starts flashing. Once charged, they won’t do this again unless you let them sit unused for several weeks.
I like how small they are. They can clip to a helmet or waistband as well as attach to a bike with the elastic bands.
