Hmm I've owned three 6 speed CL's now. 2 of the 3 needed a passenger side ballast at some point. I usually replaced with one out of a CL that was being parted out that was an 01 or 02 CL. Once replaced I never had to replace again....yet LOL. The last car I bought the inverters off he only wanted $50 for whole headlight including inverter! At that price I bought both H/L's so I have a spare.
I think the reflectors in the H/L's are set up to reflect differently for halogen vs. HID bulbs. But people put HID's in halogen designed headlights all the time so should work, just may not have such a good beam pattern. But at least you won't get pulled over LOL
