Hi - just wondering if my park lights should be on in both positions of the light switch. They come on now if I pull the switch to the first position, but are off when I pull the switch all the way to headlights. I have a 37 gmc 1/2 ton. I woulda thought you'd want the park light/running lights on in both modes - when the headlights are on, presumably it's dark out and you'd want to be seen from behind as well. Anyways, let me know if you know.
