Headlight/running light/foglight operation Options

[1970 Neun vierzehn]

On a recent thread, a forum member posed a question about the switch function and operation of his ('72/6, French market(-sounds like a coffee blend) 914. I could only surmise what the regulations and specs for that market might have required.
However, there seems to be variation of lighting interface on some USA spec cars that I've seen.
My own, unaltered '70/4 works like this. Pull the dash light switch to the first detent and the h/l buckets come up w/o h/l illumination. The front parking lights, side markers and t/ls are illuminated. Pull the switch to the next (and last) detent and the h/ls come on. The fog light switch, next to the h/l switch, illuminates the fog lights whenever it is pulled out, regardless of the position of the h/l switch.
Furthermore, I know of unaltered 914s ('72 and later) that when the h/l switch is pulled out to the first detent, the parking/side marker/tail lights are illuminated but the h/l buckets do not come up. The buckets come up and the headlights come on only in the last, final switch position. I do not know if the fog lights can be used independently of the h/l switch position, as on my '70.
Running changes? Specification changes? Factory variations? The whim of Hans on the assembly line. (IMG:style_emoticons/default/confused24.gif)
