I used the projected fog lamps that came stock off a MK3 Jetta GLX VR6. No, not my old car, but my little brother's car as he was donating it. His car had seen better days so I took what I needed before it was towed away.
Eye'ing the MK3 fogs and a spare set of stock B5 S4 fogs I had, there looked to be some possibility to making it work. Obviously I'm looking for simple functionality because the 3000k HID's I have in my stock fogs now just weren't being used to their full potential.
No pictures right now as I was working late last night why setting this up, but I plan to post a short video of what was involved. In summary all you need is:
Yes, it's low budget but it works.
Ok now what? Well guys, you will need to wait for me to post my video. Please understand that when it is up, this is just going to give you a general idea how to perform this retrofit. The point of a retrofit in my opinion, is really to make it your own. So I'm not going to cover every little step in perfect detail. If that's scary for you... time to branch out. Don't mean to be a dick but this is seriously a pretty easy retrofit.
Anyway.... don't wear out your F5 button, I'll try and get the video up this weekend if not sooner.
