Im trying to change the low beam head light bulbs in my girls 2003 Saab 95. does anyone know what holds the bulbs in? I have the covers off (covers on the rear of light housing) but i can't see,I have to feel my way around with my finger tips. I just cant figure out what to do,......do they twist?,....... is there a clip? I really don't want to break anything. The first to give me the help i need gets the 10 points for best answer. Thank you, Rob in PA.
