Looking for bulb sizes for your 2012 Ford Fiesta? This page helps you verify the correct bulb by lighting position, so you can match the right replacement for headlights, tail lights, interior lights, and other exterior lamps. Because Fiesta lighting can vary by body style and market, checking the exact position is the safest way to buy the right part.
Use this guide to confirm common bulb types on the 2012 Ford Fiesta before you order replacements. Whether you drive a sedan or hatchback, the chart below can help you identify the correct bulb for low beam, high beam, brake lights, turn signals, reverse lights, license plate lights, and cabin lighting.
Fitment can differ by trim, lighting package, and body style, so always compare the bulb in your car with the listing on this page before purchasing. Some positions may use halogen bulbs from the factory, while others may be converted to LED with aftermarket parts. If you are switching to LED, make sure the bulb size, polarity, and any required load resistors or adapters are compatible with your Fiesta. For the most reliable result, remove the installed bulb and check the base type and markings before buying replacements.
