Hi JP! Good to hear form you.
I don't know all the combinations, but here is what I know so far from research this month.
Euro - the euro W111 cars came out with the "all-in-one" headlight under one glass lens. These had all the functions, headlights, turn signal, parking light and clearance lights all under the glass. There are two versions of that and I believe the later version also includes a driving light. Not sure.
With the introduction of the 6.3 W109 car in late 67, Bosch produced the halogen "stacked headlight". It has all of the functions that JP describes including the parking light in the lower high beam reflector. The triangle lenses were amber and clear and used single filament bulbs.
US The W111 originally came out with "stacked" sealed beam headlights with no bullet lights (my personal favorite). See attached '61 US version. These had the two filament outers and should have a single filament inner. The outers (not sure if amber or clear w/ amber bulbs) had the functions of turn signal and parking light. The clear inners provided the clearance light. This what I am trying to achieve. I actually found two assemblies in OK shape that I will restore for my car. Yes, it is a '68. But too bad because I like the early look. And it is reversible for the purest down the road.
The bullet lights (or later round fixtures for the low grille cars) incorporated all three functions that were found earlier in the outer and inner triangle lenses. Therefore the triangle lenses on these later cars, had no provision for lights.
BTW, try this site for parts.
