Hi all, just bought a 2000 E320. I would like to convert the halogen headlights to xenon. Any suggestions as to where to buy the conversion kits? Are the headlamps (the glass shell housing) the same between the halogen and xenon? Only that the lights are different? I ask that because HID4Less has just the bulb conversion kit with ballast. Or are they different that I should buy the whole set up (replacing the headlamps completely) from Evosport for $1,699? I also saw ads from autoclass.net where they sell e-class xenon headlamps for 499.00. Are those genuine MB/Hella parts? even if I buy that, I would still need to find the plug n play adaptors along with the ballast right? Can anyone point me to the correct direction? Thanks so much.
