Don't put HID's in a halogen housing. You won't be able to see as good as before since the light pattern will be scattered everywhere- not focused where it should be. You'll also be blinding oncoming traffic.

You might find plenty of forum post approving of it, or have buddies telling you that it's ok and that they "never get flashed"... it's really easy to find uneducated advice, is that the kind of info you want? It's illegal for a reason.

Why do you need such bright fog lights? Do you live somewhere that has thick fog often? Fog lights are only to be used when you need to light up the area **directly** in front of the car so you can see to stay in your lane. They're not made to help with down-road vision at all. Don't waste your time/money trying to upgrade the fog lights if you don't actually need fog lights. If you need more down-road lighting then you'll need driving lights that only come on with your high beams.

If you actually want better performing lights then you'll need to upgrade your wiring, housings, and bulbs. Not just throw in HID kits... those are not an upgrade in any measurable way. You might get some "cool points" from your buddies who don't know any better, and tickets if the local cops know that you have them.

If you're wanting upgraded lights to be able to see better then there are options out there. Let us know what you're trying to do and we'll help.
