My buddy just got him a 2010 A5. It has the standard halogen lights and of course no led strip. Well he wants the led strip. He is looking to purchase this:


He likes the black housing but willing to to stick with chrome. I saw the e-codes on pure motorsport so Im gonna try to convince him to get those. What else does he need to make those ecodes work? I saw the halogen to bi-xenon harnesses on kufatec but i was a lil confused which one he would need [confused]. I think he gonna need the harness for any led headlight he goes with right?
