3000k HID would def. have more Light Output than the Bulbs you got from me in Foul Weather, but then also, Heat would come into Play with the Housings you have.
Sierra Fogs are ALOT Smaller than Silverado Fogs. So if you aren't having any Discoloration or Peeling of the Chrome with the Halogens, you should be ok with HID.
I see no problems running the 9005 so far...
BTW sorry for the hijack oz...
