Absolutely satisfactory and adequate.

Attaching the lighting is a breeze and done in five minutes. The components are firmly seated there where they should sit.

The illumination is perfectly adequate and definitely Alltagstauglich. The backlight is very glaring and visible from afar, the front light is something in the width and very good forward. Good lighting range. I can not say anything because I rarely go with this bike in the dark and the lighting is more use for the sporadic over the term.
