I agree with Rexor20, I have a 2010 GS and pulling the mirror off is NOT an option. This must have been one the the subtle changes over the years. However, I was able to tilt the mirror enough to loosen the lower outer screw. Once loosened, I was able to use a plastic pry tool ($5 from Autozone) to get the light housing out and change the bulb. The first side probably took me 15 minutes and the other side took me less than 5 mins. As Rexor20 pointed out, a credit card is just too pliable to get the job done using this method.
