re:  I believe another term for 'city lights' is day time running
lamps

No, not the same concept.  The 5w bulb is not enough and is in any
event the only thing there is for what we call in USA parking lamps.
The orange units have single filament bulbs on Euro Vanagons
(Transporters) for turn signal only.  Daytime running lamps are a
Canadian concept also adopted in USA by GM, Volvo, and VW to
rationalize North American production.  Headlamp filaments are used,
sometimes at lower voltage.  I'm uncertain, but the equivalent of
daytime running lamps may be used somewhere in Scandanavia as well,
and the original concept had to do with lots of snow, sun low in the
sky--northern latitude stuff.  We motorcyclists in the USA hate them
because we become invisible again as more cars have lights on in the
daytime.  I  make Saturn and other GM owners see my brights when I
meet them on a city street in daylight to protest GM's stupidly using
the highbeams for these lights.  Hope my Vanagon's Hella H4s, mounted
high, help them see me coming. Can't wait 'til I get my SA grille
installed.
