For the 2018 Ford Fusion, headlight bulb fitment depends on the factory headlight type. Models with halogen headlights use an H11 bulb for the low beam and an H9 bulb for the high beam. Models equipped with LED headlights use LED units for both low- and high-beam functions, so they do not use the halogen bulb sizes listed above.
The front fog lights, daytime running lights, parking lights, and front and rear side markers are LED. Rear lighting is also primarily LED, including the brake lights, center stop light, tail lights, and rear turn signals. The front turn signal is 64132 on vehicles with halogen headlights and LED on vehicles with LED headlights.
- Reverse light: 921
- License plate light: 168 or 917
- Dome, map, and trunk lights: LED
Verify whether the Fusion has halogen or LED headlights before ordering, since the low-beam, high-beam, and front turn-signal specifications change with that configuration.
