Hitman said:Another benefit to wiring the fog lights up independently: They will stay on even if you have your hi-beams on. I've been in situations where I could use all the light possible, which is not too bad with the hi-beams and foglights together.
In many states, that is illegal. The foglights must turn off when the high-beams come on. On every car I have seen, the foglights went off when the highbeams come on. The 4Runner does this and so does the X5. The X5's foglights do not stay on all the time, you have to manually turn them on. When they are on, you see the little foglight icon on the dashboard go off when the highbeams are on and come back on when they go off. This is to prevent you from blinding oncoming traffic.
