2005 Ford GT Bulb Sizes
2005 Ford GT stores 13 bulb-chart rows across 13 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
What fog light bulb does the Ford GT use?
2005 stores H1 for fog lights.
What turn-signal bulb does the Ford GT use?
Halogen-configuration turn signals in 2005 store 3457A, LED. An LED-headlight configuration can list LED instead of these bulbs.
What brake-light bulb does the Ford GT use?
Halogen-configuration brake lights in 2005 store LED.
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.
How are HID bulbs handled?
D-series capsules such as D1S or D3S are HID. Exact catalog matches for those positions use HID products, not halogen bulbs.
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 GT bulb chart change by year?
Bulb rows are stored for 2 years, 2005–2006. This page shows 2005. Choose another year to see that chart. Years are not collapsed into one bulb list.
