They do fit perfect or thats what the box or advertisement tells you??? Listen man, since you obviously lack some experience in the DIY/Aftermarket world (did you take a crowbar to your old lights? The engineers who designed them would not approve. .), you should probably know that most aftermarket manufacturers aren't so concerned about satisfying industry standards or honda's engineers when they crank these things out. A lot of aftermarket lights have fitment problems and just because the box says they don't doesnt make it so.

Also, the blue effect you see on the box is contingent on the angle the picture is taken from. If you have ever seen a prism and the way it gives off a direct beam of white light, you'll know that the different colors of light are given off in different directions because each color has a different wavelength and therefore a different energy. You are likely to see many a funky color from these lights no matter how cool they look in the box. Like some others have said, yellow and green. . .

they also present legal problems depending on where you are. Take the advice of people on this board man, they've all done this stuff, some of them more than a few times. . .
