It always a good idea to change the lights on a car. As people put different ones on a car, makes the car more of a one off. They are really nice set and would set off your black civic.
I was trying to get hold of these for my civic, they dont sell them in the UK, the cheapest i found them for was $180 (around £100) I think they look nice
the ones ax but up are best, second best option wud be to do somethin unique to ur existin ones mate, ie tint them all red. Any mod is better than standard.Up to u dude
