There are four modes: continuous light, slow flashing, fast flashing, from. Here, it is clearly mentioned that the lighting performance for such a small part is impressive. The only light at the wheel but I would never use.
The two supplied CR2032 button cell have now held me tight 10 months, and I have only used the rapid flashing mode, since it contributes in my opinion the best for visibility.
If you consider that virtually identical models of other providers are selling on Amazon in places INDIVIDUALLY 12 to 15 euros, I grab the head. The Froglights be shipped from China, and are therefore a little longer on the road. I think I had to wait about two weeks, which I find absolutely fine, however.
Since I have lost one of the Lights (out of a backpack for carelessness, not because of the holder), I've just fresh new two couples ordered them if necessary to have in reserve.
