I recently managed to replace the Low beam combination D1S bulb on my 05 XJ8 without having to remove the front bumper. This operation requires both a lot of patience and time but can be done. If you are wanting to attempt this replacement, I'll be glad to give anyone a detailed list or explanation before they attempt to do so.
