I switched my Jeep's original headlamps to HID, but as if often the case, the clearance behind the headlight assembly isn't great. I found it very difficult to get my hand around the bulb to turn it, so I came up with this little wrench that could give me leverage on the bulb with just my fingertips.
This is designed to fit Kensun 9006 type HID bulbs, but I'm willing to bet it would fit around a good many HID bulbs on the market; most of the ones I've seen on eBay and such look identical to what I have.
