Silly Q about the headlight bulb

The passenger side headlight bulb is blown on my 96 LSI..Any ideas how to replace it? do you do it from the front or the back. I disconnected the switch from the back and took off the 2 screws on the metal retaining clip, but the plastic headlight is still enclosed and can't get to the bulb. On another note my Metro just made a 3000 mile trip non-stop from Seattle to NYC @ 70 MPH with no problems other than drinking about 7 Quarts of oil. Metro has 135K miles.
Thanks

Bulb comes out from the back. Turn the lock counter clockwise and wiggle out the bulb.
