This page covers bulb sizes for the 2012 Ford Expedition and is organized by lighting position so you can verify the correct replacement before you buy. Whether you are changing a headlight, a license plate bulb, or an interior lamp, matching the bulb to the exact location is the easiest way to avoid fitment mistakes.
The 2012 Ford Expedition uses several different bulb types across the front, rear, and cabin lighting system. Because trim level, body style, and lighting package can vary by market, it is smart to confirm the bulb position on your vehicle and compare it with the chart below before ordering replacements.
For the best fit, compare the installed bulb with the listing on this page before purchasing, especially if your Expedition has been modified or equipped with an aftermarket lighting kit. Some owners replace halogen bulbs with LED versions, but LED conversions may require the correct base, polarity, or load management to work properly and may not perform the same as the original bulb. Trim and package differences can also affect interior and exterior lamp sizes, so checking the old bulb first is the safest approach before you buy.

The front turn signal bulb is 3157A.

Because trim level, body style, and lighting package can vary, the bulb installed in your vehicle may be the best confirmation before you order a replacement.
