You can find less expensive LED headlights online from Asia (and maybe elsewhere) that just have a regular symmetrical lens for a lot less that would be illegal in Germany.
PS I can recommend the Supernova brand. I used one for over 10 years, constantly on, until my 1992 Trek Multitrack was stolen in Ventura, California, last month.
I learned here on bikeforums of a Chinese made light that claimed to comply with the German law. It sold for between $8 and $16. Over a year or two, I bought 8 of them. The beam shape was excellent. Two of them stopped holding a charge early on. I still use them but they are now out of production. They are tiny, and the battery lasts a few hours. There are very few battery powered lights with shaped beams which is a shame to me. I think Cateye made one until fairly recently. I guess the demand is low.
