Alright Ive been looking around and thinking about retofitting the is300 fog projectors. It doesnt seem too hard but dont know about fitment. I couldnt find much done on the 04-05's so if anyone here has done it let me know.

 

I havnt actually seen a is300 retro, but I know you can fit a bosch mini h3 projector in there. Have a look at hidplanet.com. you will need to register to access the forums. under the "university" section, there is a stickie for projector size. have a look around and see what you think might fit. hope this starts you in the right direction
