Once set makes the spotlight a very good figure. The installation is quick and easy with a few simple steps. The headlights projected a sharp edge to the street lights and the field of view to the front of terrific. I got it set somewhat higher to see on unlit because enough. Here, the light remain predominantly non-glare and I had to plug in any wild hand signals and flashers from oncoming traffic;) As a motorist you know the problem even, nothing more to see behind a bicycle. The parking light function is also great and very bright. In style stand there are mainly the two outer LED and in driving the inner. As Dynamo I use a Shimano hub dynamo. Rain was the lamp so far also not mind and saying he pretends not when things get a little more hilly. So just buy it!
