Thanks for your responses. As per your questions:
1) mrtosh: The 05 cherokee uses an h10 bulb for the fog lights meaning that you would need to order H10 Jet yellow halogen bulbs
. These are halogen bulbs (not an HID kit
) meaning that no ballast and additional wiring is necessary. The part number would be "230010JY"
2)NHWK05: Your vehicle uses a 9006 bulb for the low beams and an H10 bulb for the fog lights meaning that you would need to get a 9006 HID Kit and an H10 HID kit to to upgrade both. I would suggest going with 4300k HID kits to get the brightest and whitest possible light output. XenonDepot carries 2 lines of HID kits. Please view this link for more information:
