    Lighting/ electrical problem

    I have a 2004 cts and the lights flicker very quickly on occasion usually only at idle. When i turn of the car and leave the lights on the flickerin stops. I thought this could be a problem with to much draw on the main battery for my apline 10in type-r which is wired to a 500watt mono amp. However i installed a second battery (a dry cell deep cycle audio system battery) in the truck. And i noticed the same flickering today. Anyone else think this may be my alternator like i am thinking? I got a voltimeter out before i did second battery and it was 14.3 at idle and with sub blasted it would fluctuate between 14.0 and 14.6. Which since the voltage stayed above 14 figured my alternator was doing ok i was just curious of any other things it could be. After i got second battery in at idle the voltage on main battery was up to 14.7 i didnt get to test anymore than that.

    This has nothing to do with warranty, extended warranty, or recall problems.

    Moved to the proper CTS forums.

    Try putting a Capacitor in. I have a 1000 watt amp with two ten inch JL Audio's and I barley get the lights dimmed.

    It could simply be that the HID bulbs are old, they are 9 to 10 years old if they haven't been changed. A fast flicker is classic sign of age.
