Kia Sedona headlight bulb repalcement?

My right front headlight seems to need replacing. The light goes on and off when I close the hood. How do I replace the headlight bulb on the right side? I looked under the hood and there are a lot of screws and plastic parts and I do not want to break any of these parts. Or does the whole light assembly have to be replaced? The vehicle is a 2002 Kia Sedona.
