I have confirmed that the fog light bulb is in fact an H11, just like the low beam headlight bulb, however, it is an LL bulb. I imagine that they made it an LL because it is supposed to be hard to get to so you don't have to replace them very often.
I found this NOT to be the case. I was able to get to the bulb easily without getting under the vehicle.
Right behind the headlight housing, there is plenty of room to reach down and you can feel the back of the fog light bulb, just twist and pull it out and the wiring is long enough to pull it up and drape over the headlight so you can replace it easily. Nice that they designed the fascia so that the fog light is higher up closer to the headlight so you can get to it.
Now with this information, one could get 2 sets of H11 bulbs (any color, brand, whatever) and the light will match. If only the headlights were the projectors as well.
Although the fogs are LL's, they are still 55 watters. If you got regular 55watt H11's, would they be any hotter and melt the housing or wiring or would they produce the same amount of heat so you have nothing to worry about?
When I get my Audi LED's, I will look into how to remove the headlight housing and let you guys know so that ohnoesaz can prepare for removing it when he gets his Grand Cherokee projectors from the dealer.
