What bulb do you need for the rear blinker on a 2001 Ford Mustang?
A 2001 Ford Mustang's rear turn signal (blinker) bulb is typically a 7443, also known as a W21/5W. However, it's always best to verify this with your owner's manual or a parts store using your VIN number to ensure complete accuracy. Different trim levels or regional variations *might* have used a different bulb.
