'91 Storm low-beam headlight blown!

My son has a 91 Geo storm with a blown low-beam. It's been a while since I've worked on sealed beams. How does one go about changing out the light? Also, do the lights have to be on (to lift up the headlight covers) so that they can be changed out? I've seen 2 screws up front, but they look like the alignment screws to me.

Help!

One word of advice is to don't mess around with the headlight flap. I messed around with mine and sure enough, it broke, so I had to use super glue on it and it kept breaking so I just epoxyed it (which is a weird thing to do) but it worked none the less.
