The Ford Mustang is an icon, but one area where many owners quickly look for improvements is lighting. Older models rely on halogen headlights that tend to dim over time and struggle to illuminate dark roads. Upgrading to LED bulbs can dramatically transform nighttime visibility, enhance safety, and give your Mustang a sharper, modern appearance.

This guide covers everything Mustang owners need to know when choosing LED bulbs, from confirming bulb sizes to selecting the best SEALIGHT headlight and fog light options. You’ll also find recommendations for additional lighting upgrades, expert insights, and direct links to SEALIGHT’s Mustang LED bulb collection.

How Can I Confirm the Correct Bulb Sizes for My Ford Mustang?

Bulb sizes vary significantly depending on the Mustang’s year and trim. For example, early‑2000s Mustangs use 9007/HB5 headlights, while mid‑2000s models switch to H13/9008, and 2015–2020 models feature HID D3S/D3R bulbs.

Because of these differences, the best way to ensure accuracy is to check your owner’s manual or look at the current bulb you're replacing.

You can also use SEALIGHT's Mustang Bulb Size Finder, which quickly matches your car with the correct replacement:

Always confirm your year, trim, and lighting configuration before ordering. Some key notes about Ford Mustang bulb size:

Headlights

  • Mustangs before 2018 came with halogen (9007, H13/9008) or HID (D3S) options.
  • From 2018 onward, most models use LED assemblies that are not serviceable by bulb alone. The whole unit must be replaced.

Turn Signals, Brake, and Reverse Lights

  • Older models often use 3156/3157 bulbs for signals and brake lights.
  • S550 models (2015+) typically use 7443 or 7444NA.
  • Post-2018 Mustangs may use LED modules or 7440/7443 bulbs for exterior lighting.

Interior and Marker Lights

  • Common sizes include 168, 194, 2825, and 74 for dome, map, and license plate lights.
