Rear lights/ indicators and foglight
In the near future our vehicle is going to end up in a country where the rear fog lamp is a must. One needed, on drivers side. Is the wiring and the bulb or place for it already there, if I find the switch from somewhere?
Or is the US-model rear light with out that rear fog option/possibility completely, and I might end up changing both rear light units ?
$$$Also a small possibilty that the red rear indicators on our GLK are not OK there, they should be orange... can the colour of indicators be changed by just re-programming ? As I heard a rumour in an Audi it can be done by programming?

Not sure yet if all is needed, but was warned about these two potential issues facing us eventually.
Also saw a similar switch on e-bay with 2 push buttons on left side. Interesting.
The double push button is similar, but one one is fir front fogs and the other for rear fog light.
Have to some investigations.
And works from that separate push button, left side of round light switch, as was mentioned.
Also as was said here too, with the LED strips in front, no fogs there at all. Only at rear.
Which is just what I need ! Happy now.
While I was investigating the way the rear light work, got a bit puzzled with the brake/indicator combo. The rear lamp unit has 2 red areas, clearly visible. Only the top section is used, it works as brake and indicator, both red, naturally.
What is the lower red part then for ? Can even see the LEDs there ( I think... ) , but they don't serve any function at all.
