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
Mass: 19 g (with washers, nuts, bolts).
Size: 64.0 mm width (optic 38.0 mm), 18.0 mm height, 20.5 mm thickness.
Light source: 1 red LED?
Mounting method: On the rear rack (or under saddle with mount there).
Cabling/connectors: 2 connectors for a dual strand cable with 2.8 mm plugs.
Construction: Plastic, housing looks to be glued, with stainless steel mounting hardware.

Price: ca. € 18,-

Beam shots

See the camera settings page for more on the setup and settings to make pictures of the beams of taillamps.

Comparing taillamps



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