i retrofitted the LED angel eyes into my P46's. I suggest that you carefully remove the LED circuit board from the LED angel eyes and put them into the existing P46 angel eye rings (they should just clip out).
It was a pain to do, but looks cleaner. I was plannning on gluing the LED angle eyes in place, but it would look messy and unprofessional as the areas where the old angel eye covers clip into seemed to show around the new rings. Also if something went wrong with the angel eye, you might have problems getting it back out later.
