Hi guys. Picked up my 57 plate S3 today. Mega chuffed! I've already decided I would like to swap the front headlights (think mine are adaptive bi xenons?) to adaptive xenons with the LED DRLs these are my current headlights ive had a search and can't find a definitive answer. I was curious on all in cost, where to get parts and is it a straight swap? thanks. If this is a common question my apologies, link me to the correct answer, I did search but didn't find much.
