I have a pre facelift S3 and I have been recently been given offered a set of facelift A3 headlights for the car. As mine has the standard xenon's I was hoping to split open the two sets of light and swap over the internals. Has anyone here done this? Despite the headlight and dipped beams being in opposite positions my primary concern is the A3 projector unit appears to be bigger than the S3 xenon unit. Both sets of lights are Hella units. Before I get suggestions of just putting hid's into the facelift A3 lights, I'd rather keep the xenon's - hence the reason I'm trying to swap them over.
