Replacing a headlight in a '92 GP SE...?

Ok so i was driving home and noticed my light was dimmer on the left. One of the headlights on the left was out( i have the SE with 2 sets of 3 headlights). My light all the way to the left if you were driving went out. Does anyone have any tips on how i could change it or a site that gives a step-by-step? Help would REALLy be appreciated.

actually now that i was thinking about it is probably just he bulb i would need to replace at least im hoping ive had some luck with this car. Lets see got it way overpriced at around 3000$ and bought it with a cracked windshield, bought a new one, new alternator, battery, power steering went out, replaced brakes and rotors on all tires and thats about it but more COMING@!
