@R99 Good question! In Germany werden don't need that light's.
On my car at the moment the DRL's in the main headlight are ALLWAYS on - when the headlight position is set on Auto or OFF. The rear lights are not on when the car is in these modes.
If you put the headlight switch to sidelight then the DRL ring in the headlight turns off and the LED sidelight in the fog light housing (in the bumper) comes on and the rear lights also come on.
If you put the headlight switch to ON then the DRL ring dims down and the LED headlights come on, the LED sidelights also stay on too.
Is that the same in Germany?
