what size does the 04 cavalier take  for the exterior bulbs
 
exterior bulbs??? there are a lot of those specify which one; headlight, turn signal, foglight, brakelight, license plate light
 
If you're talking about the headlights, it's H11 for dims and H9 for brights, just like my GTO.  They are kind of a pain to find, and more expensive than the 9005, 9006, etc. bulbs like Cavys have.. Oh yeah and Sylvania doesn't make them.
