I have a RX330 2005 and am having problems with a bad seal and headlight not working. I have replaced the bulb with no result. I have since found out that the whole headlight has to be replaced. My headlight has the HID and AFS. My question is, can I switch from the HID AFS headlamps to a regular halogen headlamp? Upon taking the headlight out and looking around I did find what looks to be the factory harness coming off the main headlight harness with plastic caps on the connections. Does anyone know how I would go about doing this? I have called several dealers and they don't want to say if it can be done but one said a customer did it and found the information on line. I am searching but the only thing I seem to find is how to convert the headlamps from halogen to HID. Any suggestions of where to search or any advise would be greatly appreciated. Thanks
