Did you buy the High/Low kit, or just a basic HID kit? I don't know if there is more than just a bulb difference between the two kits, so buying the bi-xenon bulbs might be a waste in your case.ok, i bought a xenon hid kit and when i hooked them up to my ss i noticed that onli the high beams workd. no low beam at all. can i buy just the hi/lo bulb and plug it into the ballast and it still work with both, high and low levels?
