someone without factory fog lights might be able to get away with it, i don't have them on either truck and have been thinking of getting a box for each due to all the deer collisions, the county i live in leads the state of Va. for deer collisions, that was told to me by my ins. man after a 7pt buck hit my dad and totalled the taurus... I know i have some issues getting the 92 inspected after i bought it, mechanical parts steering, light lenses ect, as for low or high beam they checked on the lights on low beam. . and believe it or not they wouldn't pass my inspection due to the truck not having the tag light lenses over the lights and both lights were working. Each place is different, most worry about brakes, and the normal functioning lights. . others could care less as to them it was working when they inspected it so its no skin off their rears.
Also i found out any additional lights added to any vehicle in the state of Va. must be working at all times regardless if they are factory or installed by you ie. . extra marker lights, etc...
