Ah I see now. Back in the 1990's, most cars (in the uk anyway) had lamps like first photo. A parabolic mirror with a filter in front to create the correct beam pattern. In the 2000's cars and bikes started to do away with the filters and create the beam pattern using complex mirror lenses behind the bulb with clear front glass, just like the left lamp on the bottom picture and just like the late FZS's. This gives a greater light output. Recently the trend is to use "projector" style lamps, with ground glass lenses like pictured. I've never seen any aftermarket projector conversions for the foxeyes myself.
