That's correct :)
I was first going to use IS300 headlights as they can house the whole projectors and still have the factory sealing caps mounted. If someone has a picture of the back of the headlights I can show what I mean. However, their downside is that, unless you fit them to a 2002 model or newer IS200 (at least in Swedish, as they have the same headligts as IS300), the leveling motors will not work. You would have to manually adjust the headlights with a screw driver. Also, the car needs a bit of modifying to make the IS300 headlights fit.
Yesterday I was going through a lot of boxes in my apartment when I found my old experiment headlight used to test how easy it would be to spray the clusters and fit angel eyes. I took it apart and discovered that it would be perfect for projector retrofitting. The leveleling motor will still work just as usual and the only problem I can see is that I will have to make a new rubber sealing of some kind. That will be a later issue. I'm hoping to start working on my projector project during next week. I will update my thread when I've made some progress. Cheers
