At the urging of my wife and because I already have a good B & U Scheinwefer have at the wheel, I was looking for a good light source. The purchase of this item has paid. In addition to the parking light he has a daytime running lights and the built-in sensor automatically switches the light at night in the full mode (both can also be switched off). The cone of light is very bright and relatively homogeneous. Also in front of the wheel, it is not dark. The field of instrumentation from 10 - 15m before the bike is very bright and well-lit. Will replace my already good B & U by this. Absolute buy recommendation!
