I really love the Liberty Renegade 4-light Bar. It's molded plastic and looks clean. I approached my local Jeep Parts Counter and they did a little research for me. Sadly, the rooflines are too different for anything but a total custom installation. With it being over $400, I'm not sure I want to try a custom install...
Not to be discouraged, I have found the following option:
Mopar part #s and description follow.
Roof Basket Carrier, Mounts to production side rails; includes air deflector and logo.
Complete wiring kit for installing up to 4 Off- Road Lights to the Mopar Accessory Roof Basket.
Mounting Brackets for adding a pair of Off-Road Lights to Roof Basket
Set of 2 rectangular Lamps with Black plastic housing, 55-watt, 90,000 candle power, with Hella/Mopar logo covers
Should look something like this totally assembled:
Of course there are cost saving options, like subtraciting the install kit and mounting brackets and perhaps using no-name or cheaper lights.
Think I'm going to go for the basket and see what develops!
