i just swapped out the license plate bulb for a set of white t10's that i got on deal extreme at $3 for the pair, and the are BRIGHT. very classy looking, makes the car look so much cleaner.
i wanted to comment on the process in case anyone had difficulty like me. the recommendation on this thread, as in the manual, is to use a flat head screw driver with cloth or tape to get the lens off, but i found it much easier to use the smallest flat head in a mini screw driver set, like the ones used for eyeglasses. use this screw driver.
next, look at the lens under the bumper with a flash light, on the sides you can sort of see where the lens clips into the black bracket that holds it in place, it's just like the lenses in the car. now, if you are righty, remove the lenses from their right sides, as it is easier to access that way as a righty, and vice versa for lefties.
to actually get the lens out, wedge the tiny flat head in the center of either side, and then push it as far up as possible. next, simply begin to push the grip of the screw driver away from the enclosure, and it may pop off, if not, use your free hand to help pull it out.
once out, swap the bulbs and test (either turn on headlights, or just use the remote to lock/unlock). if it lights up, replace the lens by inserting one side in first, pushing it up and then pushing the other side up. it will pop back in. if it doesn't light up, flip the bulb. also, the bulbs are vertically aligned, meaning the long part of the connector runs parallel with the side of the car.
even the bulbs were a bit tricky to get in at that angle, you really need to look up there, try to line it up, as close as you can, and just turn it left or right a bit to get it to go into the slot. that is all, lol!
