Need some advice. If i'd buy used xenon headlights (doesnt include ballasts,wires or such) what sort of stuff i'd need to buy from stealers to make them legal. Here in Finland you need the automatic ride-height adjuster when car starts, so the manual button which is inside the car next to steering wheel is useless. Do I need new wires or are they the same as non xenon headlights? How does the automatic ride-height thing work? Whats needed? Part numbers and prices would be great.. BTW do you need original ballasts or can u use those kits which are sold in ebay?
