You would lack the chime, but they could be tapped into a fuse that turns off when the car is turned off. Mine are after market fogs and I have them tapped into the power windows fuse, so they turn off as so as I open a door.Factory fog lights cannot be turned on without having the headlights on. If you have a good understanding of circuits and wiring you could rewire them, but you would lack the chime if they're left on. Your only other option would be aftermarket fog lights as they're independent.
