That all makes sense about the auto-headlamp-on and the headlamp switch.
Our govt also did something strange in 1986, they introduced "Dim-dip" headlights where the headlights would come on at about half power on dipped beams if the sidelights were on and the engine was running. Most of the world adopted this very quickly and it was the norm until the mid 90s when the EU said we were being discriminatory having that law and said we had to revoke it. Some manufacturers stopped fitting dim-dip immediately (mainly French) where others still fit it, even now!
Classic example of all countries not reading from the same page!
YT/Phil has put some useful links on page 2 of this thread, about halfway down :
http://www.birtydastards.com/frm/index.php?topic=28379.25Mainly for CREE headlamp bulbs and also light bars. The LED bulbs i bought for these fog lights are only about 200Lm so fall into the category for DRLs (just!) and round here they don't seem to bother too much about lighting regs - there are loads of US-spec cars running with Right Hand Dip headlamps - a real pain when driving at night! Because we drive on the left here we need Left Hand Dip. Un fortunately it seems the people that check their cars out don't realise that RHD on a headlamp lens means Right Hand DIP and not Right Hand Drive!
