Earlier today I installed my newly acquired H.I.D.'s on my '98 Cadillac Seville STS. I purchased a "plug and play" kit for the headlights (9006) and my fog lights (880) that instructed me to plug the wire coming out of the ballast into the OEM bulb wire harness and then connect the H.I.D. bulb to the ballast. I connected everything and hit the switch, but nothing happened with the headlights (the fog lights worked fine.) I remember on my last car (which I had the kit professionally installed) I notice the guy reverse the polarity on the wire from the bulbs going into the ballast because the same thing happened, and after doing that, the lights turned on and worked fine on that car (a honda accord) ever since. So I flipped the wire over to switch the polarity on this kit and the lights operated like normal (like the honda). Now tonight I'm driving home from work and I notice that every time I turn on the turn signal light, the driver side headlight would go out and I would have to turn the lights off, then on again for it to ignite. The passenger side did that once too. What did I do wrong? Do you have any suggestions you can give my or maybe let me know if I have a bad kit so I can return it (bought it waaayyyy out of town).
