Really the fog lights are not supposed to come on with the high beams selected. There's enough residual voltage running through the system that some witchcraft takes place between the fusebox and relays when you use LEDs ( lack of internal resistance...) in the fog lights that they can stay on until you actually select the fog light off position of the switch. See if their operation goes back to normal if you put the halogen bulbs back in the fog lights. There's a work around for it ( clipping the trigger wire in the fuse box harness...), but I haven't bother with it yet since it doesn't really bother me.
