I have a blown headlight on the driver's side. I have pulled the battery and unscrewed the plastic cover. Now, how do I get the doggone clip off the bulb. I can barely see the bulb; however, I think I see the clip and three screws. Do I need to loosen or remove any of these screws or does the clip just "unclip" (I'm trying to comprehend earlier advice)? Sure could use some immediate advice! Thanks.
