This LED lamp truly earned the designation headlights. For the 3rd highest power level enlightens not only the way, but a large area all around the focus. This facilitates orientation in the forest, but the large-scale all-round irradiation is the downside to the traffic routes, where one has to reckon with oncoming traffic. So it is not roadworthy (not allowed) in the highest light level. Man may make you feel using the smallest brightness level in the public transport sector has, for as the glare of the other person is little or not given. Otherwise, the lamp is good and quick to fix. The battery part can also be attached easily to the bicycle frame. Therefore my full recommendation for the terrain and slight compromise for using public roads. As an alternative for the public sector still recommends a smaller lamp on the handlebars to install and use.
