For the 2009-2012 Audi A4 (B8 pre-facelift), the headlights came in two primary types: xenon HID units with self-adjusting dynamics and LED daytime running lights, or standard halogen reflector assemblies . A distinctive feature of this era is the clear visual difference between the North American models, which include an amber side marker, and the European "E-code" versions, which omit the amber marker for a cleaner look and produce a wider, more brilliant beam pattern .
