The "V-LEDS HID 6K WHITE 4 LED 2 WATT HP M-SMT FLANK BULBS 194 168 158" will fit for sure, I have the exact same one installed but the 5K White version instead. It was kind of a tricky install for me because the wiring didn't have much room to work with when I pulled it out, But yes they work wonderfully, very bright and it creates like a 3 foot line of light behind the Jeep. I would provide some pictures but my camera is down at the moment.
This is not my Jeep since it's a WK, but it gives you an idea of the output and it would practically look the same on the WJ. This was posted by the reviewer "S1LV3R_GC_SRT8" on V-LED's. Do take note: He's using these #192 in his rear map lights as well as the dome lights, which for WJ owners, are #214-2.
