For the 2008 Ford Focus, the low-beam and high-beam headlights both use an H13 bulb. This means the same H13 fitment serves both headlight functions, making it important to select a replacement designed for the correct headlight position and application.
Fog-light fitment is listed as either H11 LED or H16 LED. Confirm the existing fog-light housing and connector before ordering, since these are separate listed options rather than one universal fitment.
- Front lighting: 3457A for the front turn signal and parking light; 168NA for the front side marker.
- Rear lighting: 3157R for the brake and tail lights, 3157 for the rear turn signal, and 921 for the reverse light.
- Additional lighting: The center stop light is listed as LED, while daytime running lights use 3157.
- Interior and plate lights: License plate lighting uses 6418. Dome and trunk lights are listed as 6411 or 6428, and the map light uses 3886X.
