So I just purchased a 2004 ES 330, and it does have the halogen headlights. I would like to switch these out for projector xenon headlights. I searched online and noticed that there is a lot of people selling the housing with the projectors already installed. I know I still will need the ballast to be able to convert it over. So I was wondering if anyone has experience with the shops that offered the headlights if it is worth it to buy from them or just get the 05-06 headlights for the car. For example these guys at TopgearAutosport. Not sure if anyone knows if they just take the 05-06 headlight housing and add the halo for effects, or it is a custom job. Thanks for the input.
