No need in removing the bumper to put on led bulbs on the fog lights look for a You Tube video how to do it super easy and since our 6ís have projector lights on the low beam HID kits is what you need
I agree. I am a complete newbie in car lighting mods, and I did it by just removing the wheel well covers (5 push tabs). No need to remove bumper.
1) Set up all the HID connections in the engine bay (relay, ballasts etc) , except the actual bulb.
2) Remove the wheel well (5 push tabs)
3) Push the plastic away, its hard and it wont break
4) remove the oem bulb and push in the hid bulb.
Only problem is you have to do it with one hand, not much space, but far easier than removing the bumper.
