For the 2006 Ford Mustang, the low-beam and high-beam headlights both use an H13 bulb. This single dual-filament bulb serves both headlight functions, so confirm the existing connector and housing before ordering a replacement.
The fog-light fitment is listed with two options: H11 LED and H16 LED. Verify the installed fog-light housing before selecting between them.
- Front turn signal and parking light: 3157
- Rear tail and brake light: 4057R; rear turn signal: 4057
- Reverse light and center stop light: 921
- Front and rear side markers, plus map lights: 2825 or 98
- License plate light: 168 or 917
- Trunk light: 212-2
Because the supplied data does not separate fitment by projector, non-projector, or other headlight configuration, use the listed H13 size for both main-beam functions and check the original bulb if the vehicle has been modified.
