I ordered the lights, because my old lights have not really illuminate anything. With the light that give the lights I am very satisfied. The maintenance achievements of the lamps can be quickly and easily attach to the bike and the Batterrien can be changed simply.
What I Negative noticed is that the holder of the taillight was dimensioned too small. I am probably easily come again against the outer edge of the rear light. The wide and by the large angle to the holder, the holder stops very quickly. The deduction of points I admit, because I think that it is possible to mount the rear light to be dimensioned slightly larger. It need not be aluminum, but slightly Dickers and better material would make the lights of my favorite.
The front light is really bright and the street lights from super. The bracket is very stable and does not slip more, once it is established.
Conclusion: If the holder of the taillight was somewhat more stable, I would recommend the two lights each. So I can only say that you should take care of directly by the holder, because otherwise it is quite annoying when the rear light falls on a tour.
