A little research today on parts needed (or probably not needed) for the conversion to LED headlights.
The headlight washer units: (the two differences, minor (a slightly different alignment pin/notch) and the "major" is the height and design of the actual nozzle unit...the spray pattern will be different (but not sure how) between the Xenon and the LEDs)
LED is the shorter (and sharper edged) nozzle
The different alignment notches/pin...whatever you want to call it
