I believe I need to get the metal portion of the screw in, amber lense; out to remove the Bulb (#330??) and replace with the new one. There were no lenses in them when we got the car. So I'm making some assumptions but I wanted to clarify before I go head an try to remove something I should not be and end up chewing one of these expensive (and Original) pieces up Any info would be helpful. Thanks! Am i correct?
