Brighter? Possibly. However, they will still be as useless as the factory bulbs in terms of what on the road they will illuminate. They'll just blind people instead. Think about it, have you ever seen a car behind you come up and you think they have crazy bright fog lights? Then they pass you and you see that it's barely lighting up the road 2 feet in front of their front bumper.
If you really want to change your fog lights, get these (obviously not the yellow chip set).

They'll be white like your HIDs (probably cooler color temp, so not exactly matching), and they'll be functional without blinding people.
