I just got a set a 96 gt foglights (from Gator GT) and Im looking for some bulbs, a thread on NASIOC said they take H3's? I have no idea what that means.

Are H3s universal? Can I walk into Pep Boys and just buy a set of "H3" bulbs or am I better off going to the dealer? I guess this is more of a lighting question than a foglight question.
