No, Joerg is claiming that ordinary StVZO tail lights that are visible from

visibility are preferable. And he is trying to confuse what can actually be
powered by dynamo with what he "remembers" seeing, back then, on inspecified
cycles in traffic.


The StVZO lights are woefully inadequate. Don't forget that you need one
that is visible in the daytime as well. You don't need a 1500 lumen tail
light, but many are ridiculously weak, 10 lumens, or even less.


I don't know if I've seen a StVZO tail light, but I've see a lot that are invisible either by design or because of dying batteries and a lot that are too bright to ride behind at night. Most fall somewhere in between and are plentiful -- from PDW, Lesyne, L&M, etc. The chronically nervous sometimes have two or three tail lights, which is kind of humorous -- unless they're blinding. Again, in sunshine, I always see the jersey first. I ride up behind someone and notice the tail light when I'm five feet away. It's like a fashion accessory.
