I own a 1999 Lexus GS 400. I am looking to replace both front headlight units. The problem is that they are self leveling headlights. I cannot seem to find any of these on the Internet because it is a specialty item. My question is, has anyone attempted to change their headlight units with a standard headlight for a GS 400 and had success? Does anyone have any insight on this? Thank you!
