okay, while it may not be for my truck, i do not know what the issue may be, and you guys on here are very knowledgeable so i figured I would ask.

I purchased some HIDS, with the ballasts and all for an 09' stang. The lights were connected originally and they began to flicker once the car was on, so i connected a harness (i believe thats what its called that connects it directly to the battery). That seemed to fix the problem, no more constant flickering.

Now the problem arises occasionally, not a constant flicker, but the lights would turn on and off. I cannot clearly identify a problem here, I hope one of you knows what it maybe.

FYI: (not sure if it matters or not, but the stang does have a sound system, amp and stuff on it, not sure if the battery may not be able to handle it or something) thats all it has from stock done to the electrical aspect of it.

Thanks in advance guys
