headlight prblem

[fremmy182]

while driving my headlights flicker, even if im just idling at a red light. Im not sure why it does that. I have a rough idle but i dont think thats the reason its doing that

well, if you have HID's you may need a relay harness. If you have HID's and the harness, you may need to check all your connections.

If you have stock lights, there's probably a loose connection somewhere, or the alternator isn't working to full capacity, so at low idle, they flicker.
