It's actually pretty easy...Just:
1. Unplug the wire harness from the lightbulb socket
2. Pull the rubber water seal completely off the back of the headlight
3. There will be a wire clamp holding the lightbulb in place...push down on the side that unclips it
4. Pull back clamp
5. pull out lightbulb
NOTE: When you pull out the lightbulb, it is plugged into a small plastic base...you will have to plug the new bulb into the base...remember what part of the light was facing up and what part was facing down...GOOD LUCK!! B)
