H4 is used where there is a single bulb for high and low. So no H4 for civic.
Check your owners manual, AFAIK H7 is for high beams, but I don't own a civic so don't have access to owners manual.
You can remove your bulbs and see what they are, its usually written on the bulbs whether they are H7 or H1 etc.,
