I haven't seen both the high-beam and H1/H3 filament used on high beam, but
I guess it could be done heat-wise. H4s switch from one filament to another
when on high beam, as the two together would build up too much heat.

I know the what the city lights are used for and when they're used- they
double as parking lights. One stays on (together with a taillight)  when
you leave the turn signal stalk switched on when you park the car, to mark
it in dark areas.

Very useful extra, that. I hated my old (black) Opel Kadett for not having
this feature.
