I don't mean to hijack this thread-so please just give a quick reply,
and we will leave the topic alone, but by the above reply I woudl be
under the impression that the ignition needs to be on for the
headlights to be on. Perhaps even that turning the wipers on will turn
the lights on? This is not the case with my car. Is that wrong?

No. I didnt read the diagram quite correctly.

In the W123 280E '82 diagram the headlights full beam get current via fuse 1, 3, the low beam via fuse 11,13 and are switched over with the combi lever switch. Backwards from the combi switch there are two different circuits for normal high and low and high beam warning signal.
The high beam warning toghether with the wiper goes via fuse 6 to 15 R battery via ignition key. The low beam lamp connects directly to the lamp turn-switch 56 which connects directly to battery 30. Fog front lights go to turn-switch N pull position, the other contact NSF to fuse 5 and then to turn-switch 30-battery.


I have
noticed that there is no buzzer to warn me that I am leaving my lights
on. I've considered installing a relay that will shut my lights off
once the ignition is off, but have not gotten around to it.
Incidentally, I am talking about an 84 300D.

Could be the buzzer in the dash, a one way switch diode between dash lamps dimmer and buzzer at 58, the buzzer door open switch or the ceiling lamp switch.
