Hi all hope this helps anyone wanting to change thier halogen headlights to HIDS. I found out that you have to change the headlight housing out to the one set up for the HIDS because of the projector lens being different. Here is a web site that I found that carries the assemblies that are suppose to be OEM. http://www.1aauto.com/ I'm still waiting for ones to come out for my 2015 GT but have been told that the assemblies haven't changed from the 14 to 15 models. If anyone could comfirm this for me I might be getting me some HIDS soon. Hope this helps.
