I did a little experiment today... if the headlights are off, and I push the high beam lever, nothing happens. But if the headlights are off, and I pull the flash to pass lever, it flashes the bihalogen in the lower bay. It should be noted that this is the same lever doing both functions. The bihalogen in the lower bay, when in low beam, is the fog light, which is run by a separate twist on that same lever. That lever's entire existence really is for lighting.
The parking lights... I don't even know what they are. I think it's the amber front outside corners? The amber corners inside the primary capsules are the directionals, those are a bit over an inch in diameter.
