I'm trying to change out my burnt out hid bulbs in an 02 gs300. I can't seem to remove the metal housing thing on the back of the old bulbs. I've heard its held on with clips, and I can feel two things on the side of the housing (I'm assuming these are the clips). I can move these things about half an inch but I cant get the metal housing to budge. Is there a trick to getting these off? Is there a certain way to manuever these clips to release the metal housing? Please help! Thanks
