Is pre facelift A3 S3 front lights different apart from xenons

The lights on the pre-facelift are separate from the indicators, and the xenons are in the outside of the lamp unit, inside on the facelifts.
 
prefacelift A3/S3 lights are completely difference. THe similarity is that they are 2 piece and thats pretty much where it ends!
 
thanks you 2

pre A3 glass is frosted

pre S3 glass is clear

both still 2 piece,
