Keep in mind that the screws go into aluminum anchors set into the plastic facia - similar to expansion anchors that you use in drywall. These similar to the riv-nuts that are used into the fiberglass all over the car. If you try and reverse them out you will probably just end up with about a 1/2" hole ripped or melted into the facia under each screw location. It's probably best to drill out the heads of the screws, remove the light assemblies, then carefully re-tap the aluminum anchors or replace them with Molly Bolts (Drywall anchors) or something similar. For everyone else, even if your screws are still in good shape, this is a great application for some anti-sieze compound since you are putting steel screws into aluminum anchors. I use anti-sieze on anything going into the aluminum body rivnuts. Dave Swingle
