They are so bright, that I adjusted mine slightly up and use them as headlights. I've went past a bunch of cops (plus I live across the street from the police station) and none of them have looked at me twice.

Be sure to check out your model year on www.sylvania.com since there are different bulb numbers for some of the C5 model years.

I have a 00 with fog lamps and want to do the same without a major hassle. It sounds like a plug and play thing...

Ditto on the 885's. The one problem I've found with them is the stock 899's are rated at 1,000 Hour life and the 885's are listed at 200 Hours. A significant difference but I rationalize that the 30%+ increase in output makes up for it, even if they burn out sooner.

Ain't nothing worth it once you see a HID light. Those stock light looks like **** compared to a HID bulb. Plus, the stock fogs are HID housings so they are actually made for HID bulbs.

Look at the picture below (don't pay any attention to the captions, they were for something else).
You can see that I had plenty room to mount my ballast and then some.

It's only a pain if you try and do it with the headlight assembly in the car. If you remove the headlights, you got enough room for Rosie O'Donald to take a bubble bath in there. Look at the picture below (don't pay any attention to the captions, they were for something else).
