Excellent light. Intelligent (automatic on/off if set), braking sensor, fantastic color effect on the outer ring. Interesting blue light effect during charging. I have not yet tested whether they turn off during daylight hours. I like lights that I don't have to think about and that turn on and off by themselves. Excellent quality-price ratio. I'm going to buy another one because these lights keep getting stolen.
