Prelude BB6 Type S
these guys always have brand new JDM fogs in stock. or you can try ebay. they all cost a pretty penny though.
as for the light, if you leave the housing clearand use yellow bulbs you will get a yellow light. however, it will be a pale-goldish yellow and not a pure yellow. the bulbs they make simply have a colored glass to filter the light, so they don't produce an actual yellow hue. to get pure YELLOW the best bet is using yellow bulbs, retrofitting a yellow capsule in, and putting yellow lamin-x over the housing. but that isn't what you're going for.
honestly though, putting a yellow capsule in wouldn't be too bad in your case though. you'd hardly be able to see it since its yellow and not amber. but it will require some work.
