I don't know all the technical terms but I got mine changed. Here it goes -
Reach under the body kit where the fog light is. There will be one bolt coming from the bulb housing toward the wheel. Loosen that nut. A 14mm crescent wrench is needed, there is no room for a racheting one - it's a tight space. After getting the nut, lock washer, and flat washer off push the bolt toward the fog light. This will loosen the housing assembly. Get out from under the car, grab the assembly and loosen the two screws in the back of the assembly. Then place a flat head screwdriver between the clear part and the dark back piece to gain access to the bulb. Unhook the metal piece keeping the bulb in place and the wiring for the bulb. Replace one bulb with the other. I'm sure you know this but - Don't touch the bulb. Redo everything in the opposite order. Be careful it is possible to screw the clear part to the back dark plastic piece upside-down, which causes the bulb to point up (I made that mistake on one bulb, strange effect). It is not possible to put the assembly back on the body kit upside-down though. I hope that helps-it took a little over 30 minutes to do the whole thing (I'm a novice at this)
