For the 2019 Lincoln MKZ, headlight bulb fitment depends on the factory headlamp type. Models with HID headlights use a D3S bulb for both the low beam and high beam. Models equipped with LED headlights use integrated LED lighting for both functions instead of a replaceable D3S bulb. Confirm the headlight configuration before ordering.
- Low beam: D3S with HID headlights; LED with LED headlights.
- High beam: D3S with HID headlights; LED with LED headlights.
- Front turn signals: LED.
- Rear lighting: LED brake, tail, reverse, and rear turn-signal lamps.
- Other lighting: LED center stop, parking, front and rear side markers, license plate, dome, map, glove-box, and trunk lamps.
No fog-light bulb fitment is listed in the supplied data. For replacement work, match the vehicle’s original headlight system and verify the lamp assembly before purchasing.
