The bulb replacement is pretty straight-forward once you know what to look for.
Here are the steps:

On our 2003 Forester, steps #1 & #2 were not quite as simple as indicated. First off, unless you have hands as small as a 2-year-old's, there just isn't enough room under the air intake cover on the passenger side to work. However, this is not a big problem, as the cover comes off easily with a socket wrench and a screwdriver. On the driver's side, while a small-handed person shouldn't have a problem, I needed to remove the front battery bracket to have enough room to manipulate things behind the light. Again, a socket wrench is all you need to accomplish this.
Also, I would strongly suggest that when you re-assemble things, you not be tempted to pre-install the rubber seal around bulb. Take the extra time and install the bulb in the socket first and *then* carefully replace the rubber seal around it. Even though it takes a little extra time, it makes it much more likely that you won't actually touch the bulb (which is the kiss-of-death for halogen bulbs). Lastly, prior to putting everything back together, be sure to test that your new bulb is working... There's nothing worse than reassembling things only to find that changing out a bulb didn't correct the problem. ;-)
