With some looms etc I could make them work bi xenon, heck if someone had the budget if make them a quad setup if you want to go all out.
For oem bi xenons I have mods to make them perform better, next month I am also releasing a new drl bulb I have had made for vag cars. Will be error free, no resistors or nothing needed.

What did you do in regards to OEM ones? I know ones in my A3 weren't all too great and looked into getting the clear lens from TRS
