It looks great on white.
http://thersxsite.com/kits/jdm/jdmindex.html has a lot of pics with the JDM headlights.
Just remember that those are JDM
style headlights which means they might not fit perfectly and might leak. They also won't have the bronze-black finish of the JDMs.
Pesonally I think it'd be better to save the 230+ and paint it yourself or get an RSXer in your area who has painted headlight already and you'll save some money, you could even choose to remove the reflectors, paint the headlights a different colour, etc.
