There is a lot of info about JDM markers, but I have not seen anything about flush fitting ones. On this link there are flush lights. I know that they are amber. But they just may fit with no modification and will definately look different.
I got mine off an old jdm civic/integra. Check out this link and or do a search of the information you get off the page. These are the markers I used. You have to shave a little plastic off them, but it is minimal and easy. I know they are no the most flush markers, but they are far better than what comes stock on the car. Good luck with your search.
