Nice R8 style headlights. A XenonDepot HID kit would be plug and play on your Civic. You'll just want to pull the low beam bulb to confirm the bulb type before you order as aftermarket lights usually use different bulbs than the factory lights. If you want the maximum amount of light output, I would suggest the 4300K color temperature which is also the same color as OEM HID's. As you go higher, the light will get more blue but you will get less light output.
