On my '06 (same as an '07).........On the passenger side, remove the rubber boot from the back of the housing, and unsnap the connector from the bulb and pull it out of the way.
Reach your fingers in there and turn the plastic holder ring counter-clockwise, about 1/4 turn or so. Then the bulb and ring will just pull out. Reverse the procedure to reinstall....that bulb has a location tab, so it will only go back in at a certain angle.
On the driver side you may have to remove a few pieces.....I have an SRI, so I have to remove my air filter to get to the bulb. First time I did the whole job.....I almost pulled my hair out getting the attachment ring loose.
I'll keep my guns, my freedom, and my money.....you can keep the "change".
