Chrysler calls them "Foglights" in their brochure.
I can only speak for Florida law enforcement: Statue 316.233
FOG LAMPS. Any motor vehicle may be equipped with not to exceed two fog lamps mounted on the front at a height not less than 12 inches nor more than 30 inches above the level surface upon which the vehicle stands and so aimed that when the vehicle is not loaded none of the high intensity portion of the light to the left of the center of the vehicle shall at a distance of 25 feet ahead project higher than a level of 4 inches below the level of the center of the lamp from which it comes.
Lighted fog lamps meeting the above requirements may be used with lower headlamp beams only as specified in Statue 316.237
