My wife wanted a new bicycle lights. You should be as compact, waterproof, sufficiently high speed, battery-be (as always at the wrong moment no batteries were available) and be mounted without tools. After searching and reading of some bicycle lamps tests, I have decided for the set of Sigma. The lamp holders could be very easily mounted without tools. The backlight is nice and bright and very visible (lt. Manufacturer up to 300m). The front light has a good illumination (lt. Mfr. 230 LUX) and for the City area a good range (lt. Prod. 80 m). Practically here are the three selectable lighting levels HI, Mid, Low. Furthermore, I find the light at the side very well, this increases the visibility of the page. The battery was quickly loaded (can be charged via USB) and the Batteriindikator was completely illuminated. Now the set could be tested. My wife is happy with her new bike lights and I'll set also buy myself now.
Pro Contra: good illumination so far nothing good range USB charging Battery indicator waterproof battery-free
