The camera makes them look more off white than they do in person, standing there looking at them they match much better. But not perfect, which I agree would look more "factory".I would.
I see the light's white turning more yellow (than it is now) with time.
But, I already pointed that out.
Good level/symmetric mounting.
It could very well go unnoticed as an add on....until they light up.
To get them level I used a strip of painters tap and lined it up across the top of the two parking sensors, then I used the third ridge in the top bumper trim step piece to make sure they were exact on both sides.
Followed up by double checking with my tape about 4 times before I did any cutting.
