Customer Question

I'm looking to downgrade from xenon assemblies in a 2003 xc70, and replace them with halogen assemblies. I have two new halogen assemblies, and I plan to remove the xenon assemblies completely and replace them with halogen assemblies

Will the factory HID wiring harness be a plug and play application? I assume that the ECU will have to have some changes
Expert:  Derek Werner replied 5 months ago.
The HID to halogen will not be a plug and play. And yes the central electronic module will need to be re flashed. You will have messages displayed on your dash about bulb failures and loss of communication. With the factory HIDS there is a module inside the light assembly's that the central electronics module communicates to. This is not present in the standard halogen setup.

No I am going from a bi xenon system to HID
Expert:  Derek Werner replied 5 months ago.
Oh you are talking about a aftermarket HID system? Some pictures would help of your setup so i have a better idea of what you are working with. If it is a aftermarket HID system you are trying to install then modification will be required.

Here is a picture of stock headlight assembly
Expert:  Derek Werner replied 5 months ago.
Just curious are you having a problem with the current HID's that are installed from the factory with your vehicle? I was hoping to have a picture of the aftermarket headlight Assembly you are trying to install.
