If I read the list like that, then you just need to jump the indicator light to the NSW output. Nothing else.
I don't have a specific document handy, but I'm quite confident that Google offers something suitable.
You should make the conversion reversible, in order to pass the next TÜV (German technical inspection).
Should this be a replacement for daytime running lights, or a flashing hazard light switch? The latter should clearly demonstrate the offender's intent in a serious case and appropriately influence the severity of the punishment.
