Hello, I see today that my left xenon have yellow color and not white as right.. I think I need new pair of xenon bulbs. I can not find here what type H1, H7.. or something as DS1 DS2 I need. Can you help me please? and what about light color.. I have white xenon so I think there is 6000K, have somebody 12000K xenon? I read somewhere tahat this is best to drive at night... and with xenon color about 8500K is very bad visiblity. Thank you.
