Nah, it's not hard at all. On the backside of each headlight unit, there's a gray cover. Holding the cover on are two metal clips. To get the cover off, snap the clips to either side of the gray cover, and lift the cover upwards. There is a locating tab at the bottom of the cover, so make note of that when reinstalling. Holding the bulb in is a clip that is under tension. Squeeze the two protrusions of the clip together, and move them together while pushing them downwards, and then out. It's hard for me to explain it well, but once you see it, it's self-explanatory. Make sure you wear gloves so you don't touch the new bulb. If oil from your fingers gets on the bulb, it will create a "hot spot" and the life of the bulb will decrease.
One more thing, the passenger-side headlight is a little tougher to get to because of the air-filter box. You may need to remove it if it makes it easier for you. Unclip the mass-airflow sensor, and the filter box just lifts up. Just make sure when you put the box back in, you install the air-inlet duct into its proper position.
