2003 Ford Thunderbird Bulb Sizes
2003 Ford Thunderbird stores 17 bulb-chart rows across 15 lighting positions.
Stored halogen, HID, Bi-LED, and LED rows are alternative equipment when the chart lists more than one. A vehicle uses one lighting system. Verify the lamps installed before ordering. A halogen bulb is not the replacement for an LED assembly, and an LED conversion is not shown as the OEM halogen bulb.

Replacement check
Read the number on the installed bulb or the housing. Confirm whether the headlights are halogen, HID, or an LED assembly. H11 and H11B are different. 9005 and 9006 are different. This page does not substitute a nearby designation to fill the product list.
Questions
Does the 2003 Ford Thunderbird chart include fog lights?
No fog-light bulb is stored for this year. This page does not add one.
What turn-signal bulb does the Ford Thunderbird use?
Halogen-configuration turn signals in 2003 store 3457A, 3157. An LED-headlight configuration can list LED instead of these bulbs.
What brake-light bulb does the Ford Thunderbird use?
Halogen-configuration brake lights in 2003 store 3157R.
What does an LED record mean?
A stored part of LED means that configuration is recorded as an LED assembly. It is not a replaceable halogen bulb, and this page does not sell an LED conversion as the OEM bulb for that assembly.
Can I substitute a nearby bulb number?
No. H11 and H11B stay different. 9005 and 9006 stay different. This page matches the stored designation and does not swap in another bulb to fill the product list.
Does a catalog match guarantee the bulb fits?
A designation match means the product is filed under that bulb number and technology. It does not prove the lamp, socket, or vehicle configuration. Check the bulb in the housing before ordering.
How do I verify the replacement?
Read the number on the bulb or the housing, confirm whether the headlights are halogen, HID, or LED, and match that designation. Position names that say “with halogen headlights” or “with LED headlights” are separate configurations.
Does the Ford Thunderbird bulb chart change by year?
Bulb rows are stored for 4 years, 2002–2005. This page shows 2003. Choose another year to see that chart. Years are not collapsed into one bulb list.
