Additional Notes

The Ford Focus front fog light uses the H11 bulb across all listed model years from 2008-2018.
The H11 is a single-filament halogen bulb, meaning it serves one lighting function only and does not combine multiple roles such as high and low beam within a single unit.
H11 bulbs operate at 12 volts and 55 watts, which are standard ratings for halogen fog lighting applications in passenger vehicles.
The H11 uses a PGJ19-2 base, a proprietary connector type that physically prevents incompatible bulbs from being seated in the same socket.
The H11 is an ECE-standard bulb, meaning it conforms to the Economic Commission for Europe regulations governing automotive lighting, and it also carries approval for use in the United States.
Because the H11 base (PGJ19-2) is specific to that bulb family, substituting a visually similar bulb with a different base type would result in a fitment failure regardless of voltage or wattage compatibility.
