If the battery light in your 2011 Ford F-150 flashes on and off, it could indicate an issue with the battery or alternator. Typically, the battery light remains on when a part has malfunctioned, but may flicker if a component is starting to fail. Your battery's voltage should be above 12 volts when not in use, and the alternator should charge it at around 14.4 volts when the vehicle is running. If the voltage is lower than these levels, it suggests an electrical problem. I suggest getting your battery and alternator checked to identify which component is causing the issue.
