The bicycle lamp I have attached to the handlebars of my son, because he would like to ride a bike, even in winter, a light on children's bikes, but "not intended" is. It is also primarily concerned that he is well seen by other road users. Installation went smoothly and without tools, and the light is nice and bright, so that it can be seen from afar. Otherwise we shall use the lamp also likes as a flashlight, as it illuminates the darkest corners beautifully bright!
