Very good lights. Classics. They are very affordable and effective at night. The good thing is that they are so inexpensive that you can get many or replace them if they break. It is good to use 2-3 together at the same time for better visibility.

very easy installation, keep in mind that it does not have strong light, it is simply to be seen in the dark...

They are very good value for money.
They come with batteries.
Obviously, they don't produce very strong light, but it's enough to be visible.

Beautiful, they are only made to be seen by others, something like car daytime running lights. They are not powerful enough to illuminate the road.
