Heyy.. Im so jealous I ordered a blue 2011 WRX and I have to wait for months. Your car has Projector lights..Bascially meaning there better and the light is projected in a straight line instead of scattered. You will be able to tell at night.
As the light bulbs go I would get a Sylvania( I think thats how u spell it) Silverstar Ultra or something along those lines.
To be honest most bulbs are going to produce the same light output as your stock bulbs. If you want a blue tint or something like that definitly go with the Sylvania Ultra ones.
Whats up Mike. Thanks for the reply. I actually just picked up the blue WRX in Northeast Philly. I know Pep boys has bulbs, but do you know which ones are good and work well on the 2011 model? I can't find that the bulb specs anywhere. ~ Sam
