car lights flickering, car shut off randomly, causes

car lights randomly flickers, and car behave erratically, maybe some week battery symptoms while trying to start the car?

most probable cause: ground cables.

your best approach would be to inspect and clean all ground cables in the car, look for obvious green corroded wiring, especially the main ground cable going to the battery, and were it bolts to the chassis of the car, I find this cables often to be the culprit of the flickering lights, and sometimes a no start condition.
