Headlight is easy enough. There's a round screw cap that seals the bulb and headlight unit from moisture, you unsrew it in the direction etched into the cap.
You will want to remove the wiring harness, its a PIA. You need to lift the plastic piece that connects the harness to the bulb's base.
The bulb is held onto the housing with a spring, just unhook it and the bulb should come right out.
Reverse for intall.
The coner bulbs are a pain, so I've never done it. I think you have to remove the headlight.
Whatever you do, do it right.
