Hey guys having problems with my headlights in my corolla.They keep flickering on and off when I'm driving and sometimes turn off for a couple of seconds. Sometimes happens after the blinker turns off.
I've changed;
Combination switch, and relays. Checked the wiring and it all seems fine.
ANYBODY else had this problem?
Could it be the alternator or battery by any chance?

Help asap would be really good. If you live on the Gold Coast and know whats wrong and can fix it I don't mind paying you to help me.

Thanks guys hope you can help.
