Ive seen some guys do it. but with Japanese models. not sure if the US mdoels can do that.
maybe they just too off the bulbs off the headlights

 

It would be nice simply for the fact that I don't want the fogs to turn off everytime I use the high beam. It's bad for hids to be turned off/on a lot without some "rest". This was one of the more worthwhile mods for my Supra as it allowed me to use the fogs as a sort of DRL without having to turn on the head/tail lights as well.
