I see what you are saying, they kind of have a nice contrast like the black top does. Black always goes good with white. You will like them white though I bet, if you get them done professionally the way I did (mine is red/red) it looks really nice. Either way can't go wrong. Like those tail lights. I was looking at the following, wasn't sure but yours are similar and look really nice.
