I have a set of Halogen headlights (RH and LH, not including bulbs/ballasts) that I purchased for my 08 IS250. Unfortunately I need HID headlights, not halogen, SO i need to either return these to the seller or sell them. If you're interested, they are brand new never used and should should fit your 06 IS350. Make sure you need HALOGEN, not HID. Don't make the same mistake I made. If you would like to discuss further, feel free to shoot me a private message! If I don't hear from you with in a couple of days I will just return them, so let me know.
