For the 2018 Ford F-250, the supplied fitment data lists a 9005 bulb for the low-beam headlights. The high-beam listing includes both H11 and H11 LED options, so confirm the product type and existing headlight setup before ordering. No separate projector or non-projector distinction is provided in the fitment data.
The front fog lights use 9140 LED bulbs. Exterior signal and marker applications use several different sizes, so match each location carefully:
- Front turn signal and parking light: 7444NA
- Front side marker: 2825
- Reverse light: 3156
- Brake, tail, rear turn signal, and rear side marker: 3157
Interior lighting is listed as LED for the dome, door mirror, glove box, and map lights. The trunk light uses a 912 bulb. Verify the original bulb and socket when replacing LED applications, especially where the listing provides an LED-specific fitment.
