Typical electrical symptoms owners report

Xenon/HID headlights flicker intermittently, most often at night or in cold weather, before one side shuts off completely.
A dashboard message reading "left headlight dipped" or "right headlight dipped" appears when a headlight fails, sometimes affecting both sides at different times.
Turning the car off and restarting it, or briefly shifting into neutral, temporarily resets the failed headlight until it recurs.
Owners describe the failure as recurring on the same vehicle over months or years of ownership rather than a single one-time event.
Some owners report the flickering happens mainly at highway speed or on very cold days, while others notice it in stop-and-go neighborhood driving.
