There are 3 routes you could go here and all would work equally well.
1) You could get a set of clear glass fog lights put yellow bulbs in them.
2) You could get a set of yellow glass fog lights to install.
(maybe a little harder to find the housings)
3) You could get a set of clear glass fog lights and tint them yellow with film or that fancy yellow chrome paint.
(doing the paint right can be a bit tricky, and the film will need changed occasionally)
The mounting would have to be custom though, you could either do it all on your own, or modify the current fog lights bracket to hold new ones.
