lightbulb question
I see all this talk about H4, H3, H7, etc and 9004, 9003.
Are these different names for a similar bulb? like... is the H4 and 9004 the same or totally different bulbs? I have a hard time finding H4 bulbs at auto stores... but 9004's and the likes are plenty. |

H4 bulbs are also commonly referred to as 9003 and HB2. Rest assured, they are all the same thing.
