I know the civic takes a 9003 size bulb for the head lights. Is it just me or are these kind of bulbs rare? I herd that a H4 bulb is the same thing.. is this true? Anyone else have trouble finding this size? Thanks

yeah 9003 and H4 are the same size bulb. those are just the names used in different naming systems (can't tell you the names of those systems though, cause i don't know).
