You didnt mention which year civic you are getting. I have the 5th generation (99-00) and it uses a single H4 type bulb. I believe the 6th generation usese two bulbs. So you need to tell us what are you getting.
By the way...the top photo looks like an H4, the middle one seems to be a 9005/9006 (the ones that go in the 03-05 Accord) and the bottom pic is of a 'Retrofit HID kit'. You can do without the kit...just get the bulb if you want to have the look cuz the kits are expensvie and do not last very long.
