As I commented on this thread years ago, my car is in much better working order now, so I can reveal the proper operation:

Pop-ups have dipped and main beam.
Bumpers have side lights and main beam.
If I pull the stalk gently, it flashes the main beams in the bumper (regardless of whether pop-ups are up or down).
I pull the stalk further, it clicks and holds all 4 main beams on, simultaneously switching off the dipped bulbs.
I also have fog lights in the lower lip of the bumper, operated by the centre console switch next to the cigarette lighter.

There was a crossover year for 924's and series 1 944's. Before this year, they have a switch in front of the ashtray that selects whether the bumper main beams also come on with the pop-up main beams.

I have had problems with some of the above lights not operating as described above. This is often due to dirty fuses and fuse contacts. It can also be due to worn or dirty contacts on the stalks and main light switch.
