Forum member Jeep Addicted builds a conversion harness. This will set you back about $2.3K (SRT8) including the harness which is not cheap. Another option is a blacked out halogen headlight sold on Ebay (Eagle Eyes) and use an HID harness. DDM makes a plug and play version, Diode Dynamics makes a canbus flicker fix that works with any HID kit, and Xenon Depot sells a version that might or might not work. Mine stopped working around 4 months after installed, both sides turned off. I have a feeling it was due to a software upgrade when the dealership replaced a PCM module that froze one of the front blinkers when installing the mentioned harness with SRT8 lights (I missed a ground connection).
So if you go that way, make sure you don't miss a connection, but it's worth it if you can afford it.
Here is my setup with a Morimoto Elite HID kit using the Diode Dynamics canbus fix on the low beams and the DDM kit on the fogs.
