Why are my headlights flickering when I start the car?
Start the engine. If the battery light illuminates, then the alternator is failing and is the most likely cause of your flickering headlights. This is because the alternator pulley is not able to properly charge the electrical system at low RPM and is preventing the proper draw on the electrical system by the car’s headlights.
