Hi cduluk. By reading other previous posts from you, i know that you have lot of experiences retrofit HID headlight on your vehicle and You did great job on your RX300 and 400h. I even try to PM you before i post this topic but somehow i can't do it. Thanks for your response. When you said that "do the conversion" do you mean by retrofit HID projector into my halogen headlight like you did with your RX300 or I just buy the OEM HID headlight from ebay and replace it in my car and rerun the wire. Is the halogen headlight and HID headlight from RX 330, 350, 400h are same size and bolts pattern. If i have to lose the AFS funtion, it's fine with me. Any input will be appreciated.
