Factory setting was with headlights ONLY and they flipped off when you turned on your highbeams. I did the re-wire so they come on with the parking lights. Unfortunately, that also overrides the highbeam flip, so, when my highbeams are on, so are my fogs.
That's gonna be an issue I'll have to deal with as well, if I go with HIDs. I usually just leave them on, so they flash with my alarm. I'll have to learn to turn them off so they dont do that, lol.
