You would want to power them separately from the OEM fogs in the headlamp housings though since if you tapped the factory wires to power a second set of fogs, you'd likely exceed the rating of the fuse. I wouldn't up the fuse to a higher amperage either because you risk exceeding the power rating of the individual lamps and could damage them. Put a second OEM fog switch into a switch blank spot for them or mount one beneath the dash and you'd be fine, as long as the power for each set was kept separate.
