All 04-08 GP's had the option of getting fogs. As for mine, I had a 5k HID kit in there for a while but I didn't like it because I was always getting flashed if I had them on. And I never ran them for just normal driving, just for when it was actually foggy or raining outside. I also didn't run them but for only 2 months on and off so I can't comment on HID's affect on the housing itself. Sylvania does make an 880 bulb in their Silverstar lineup. You may have to find them online somewhere though as I haven't had luck finding them in the local auto parts stores. I plan on doing a retrofit on my fogs one day. The Retrofit Source is "supposedly" coming out with an even smaller version of the Morimoto Mini H1 that would be good for small housings like our fog lights. No word on when they will be available yet.
