Yeah thats right, we have "parkers" on before our headlights lights are on at the first click of the headlight switch, but when the headlights are on (second click/full out) they do stay lit. Makes sense now running/parking lights for when you are pulled over so you don't blind oncoming traffic or make them hesitate but they are still aware you are there....not that profound :P but I've never thought about it. We just use them when its not quite dark enough for headlights or overcast and because they look cool.
