Whichever one looks better is up to you, the reason those are there is that not all countries require amber turn signals, I remember reading something about newer cobra/gt owners in other countries loosing their reverse lights because they put amber lenses in and used that spot for the turn signal. They are definately removable, I remember integras having an amber piece that snapped in in the front that everyone took out. Same with some of the front corner lights. It's probably not that hard, but you'll never know until you try.
