If you are looking up bulb sizes for the 2006 Ford GT, this page is designed to help you confirm the correct bulb by lighting position instead of guessing from appearance alone. The GT uses a mix of LED and halogen-style bulbs depending on the lamp location, so matching the right socket and function is important before ordering replacements.
Use this 2006 Ford GT bulb guide to check the sizes for the headlight, fog light, turn signal, parking light, side marker, license plate, reverse light, brake light, tail light, center high mount stop light, and map light positions. That makes it easier to replace only the bulb you need and avoid ordering the wrong part for the wrong lamp.
Fitment can vary by market, trim, and lighting package, so it is smart to verify the installed bulb before you buy, especially if your car has been modified or converted with aftermarket lighting. Some positions on the 2006 Ford GT use LED assemblies, while others use replaceable bulbs such as H1, D1S, 921, 2821, 3457A, 6418, and 3886X. If you are switching from halogen to LED, check beam pattern, polarity, and connector compatibility, since not every aftermarket LED will fit or perform the same way as the original bulb. When possible, compare the old bulb, the socket, and the owner’s manual or existing lamp markings before purchase.

Not always. Trim, market, body style, and lighting package differences can affect fitment, so it is best to confirm the bulb in the vehicle before ordering.
Yes, some positions can be upgraded with LED replacements, but you should confirm fitment, polarity, and compatibility first. LED replacements may not behave the same as the original halogen bulb in every housing.
Check the installed bulb, the socket shape, the lighting position, and whether the lamp uses a standard bulb or an LED assembly. That helps avoid ordering the wrong part.
