Taillamp: Busch & Müller Line small

On the main page I commented long ago:

2015-1-30: B&M made a miniature taillamp, the Toplight Line small, like Supernova's taillamp but with proper optics. Schmidt was I think the first to show it off in their (very expensive) version in September 2014. I'm not sure these are really interesting. Why make them so small? Too small is not good...

But I decided to test one anyway.

StVZO approval no: K920

Conclusion

The distribution of light is good but it's too small which is not good. I don't see the point of this lamp.
