well after 2 yrs of good operation, my hid's started acting funny and now they don't fire at all, so i ordered a relay harness. since it's for only low beams, could i add fog lamp hid's in the future?

Yes, but not on the same wiring harness.

that's what i was thinkin but wasn't sure.. is it fairly common for folks to run 2 seperate harnesses? or a bixenon?

You really should only need 1, but 2 is fine if you want to run them.

An afthermarket HID unit was in my '04 C5 when I got it and acts up occasionally. After a lot of "head scratching" and hit and miss replacment of relays, etc. (even a ballast which wasn't cheap, $100)) I found the problem. In the wiring to the special bulb there is a twist connector that resist you unscrewing it apart. In it is a "brush" type of electrical contact that fries itself over time. For some reason it's the driver side on mine, the passenger side has not been a problem. Next time I'm going to direct wire it and seal it up with double sided waterproof electrical tape.

ok so i removed my headlight assemblies and my balasts to inspect everything and one of the wires to the right hid bulb was cut. spliced it and gonna install relay harness. {on cell. continue next}

so my question is... could the single cut wire on the right light have been affecting both headlights? all the connectors appeared ok
