Thank you RichardV6 for the excellent description. You gave me the courage to try it as well and I succeeded! Symptom was that I could not toggle between high beam and dipped beam. It just went dark instead. Failure after 30000km. Trad Plus4 2019.
I managed to access the copper strip for the horn without removing the steering wheel. Replacement part for the light stalk is a Lucas OEM STC4017 from www.landy-scheune.de

BTW the copper horn strip can be ordered as a Honda Civic 1987-1992 part 35259-SH3-A02 (Made in Japan)
