dont know if you can put angel eyes on std projectors... don't see why not. something to consider, though, is that if they are plastic tube, and placed directly in front of the projector, over time they may melt / discolour / yellow due to the heat from the globe. They do get damn hot in there.
I think all GTSt and GTR came std with projectors; only the GTR N1 came with lighter square lights (better than GTS), and GTS with cheaper square non-projector lights.
