First post...wooo me.

I have a 2013 F30 330d with the bog-standard headlamps (H7 bulbs and 5w capless sidelights). The lenses are all scuffed and cracking and really let the car down so I plan on replacing them, is it possible to replace them with the higher-spec lights with the LED sidelight (presumably xenon or whatever headlights) or would it require control unit replacement/upgrade and additional wiring? I work for a German HGV manufacturer so I'm fairly used to the way they like to overcomplicate things and hinder retro-fits.
