I'm at work, so can't take a photo. I just ran out to my car... I'm assuming you got the 2 obvious screws. The 3rd is hard to miss, I had some trouble the first time I needed to replace a bulb. The 3rd is down between the back of the headlight and the battery. But down inside, think at the base of the battery. Stand above the headlight looking straight down, then lean into the engine bay a little, you should see it. The passenger's side is even harder, as it is hidden in some cables.
Once you locate it, just use a longer screwdriver and unscrew it. Then pull the whole headlightassembly out the front. the wiring and bulb sockets will be obvious on the back. Twist the bulb housing to get them loose.
Hope that helps.
