Email bounced back. Sounds like you removed the screws that hold the housing, not the cover. The cover screws are 5mm hex screws.
Check out these instructions I posted in another thread:
Basically, I'd recommend removing the wheel for your first install. Then remove the front wheel liner. The housing will be exposed. You then have a couple of options. One, simply remove the three hex bolts, which will allow you to take off the plastic housing, exposing the assembly. The bulb is held in by a clip with two prongs which wrap around the bulb and snap into place. NOTE: Make certain you wear clean gloves when handling the bulbs - oil/grime will kill them. It's much easier IMO to remove the housing as well, as there's not a lot of room in the headlight cavity to work with the clips. There's a single screw inside and three more underneath in the proximity of the hex screws. In order to completely remove the housing, you need to unhook the courtesy light bulb and the high beam bulb. Do not remove these bulbs, simply unplug them, taking notice of which way the wires face. Remove the housing. Note the way the flat end of the bulb base rests against the post on the housing. Also note how the two "bumps" on the bulb base insert into the housing. Carefully unclip the... clips. Insert new bulb. Reclip. Reconnect the plugs, and carefully lower the assembly (if removed) back into place. Careful when screwing in the inside screw - it goes into a busing which can easily be pushed through. Reinstall all of the screws/hex bolts underneath, being careful not to over tighten the hex bolts which hold down the cover. Reinstall the wheel liner, then the wheel and enjoy your new headlight.
Let me know if anything is unclear or you need additional help.
