Nice job! Next you'll be changing your oil and so forth. Or not, but it's amazing what doing your won simple car repairs does for one's confidence and actual ability.
Side note; it's often good to replace the same bulb on both sides of the car while you're at it. The other one will likely burn out soon since they get about the same or exactly the same amount of use. Also, some new cars have sensitive bulb monitoring systems that will react to different brands/ages/wattage of bulbs in each side.
