What bulbs are in a 2018 F-150?

What bulbs are in a 2018 F-150? In short, bulb types vary by trim and options. Base models with halogen headlights typically use H13 (9008) bulbs for the low and high beams, while higher trims with LED headlamps use integrated LED modules instead of replaceable bulbs. Fog lights are usually H11 halogen on trims without LED fogs, and rear lighting often relies on a common set of bulbs (with LEDs available on some trims). Always verify with your owner's manual or a VIN-based parts lookup for your exact configuration.

Headlights and front lighting

The front lighting system on the 2018 F-150 can be halogen or LED depending on the trim level and factory options. Below is a breakdown of the typical bulb configurations you may encounter.

Halogen headlamps

• Headlights: H13 (9008) two-filament bulbs for low and high beams.


• Fog lights: H11 halogen bulbs where fog lamps are equipped.


• Daytime running lights (DRLs): usually integrated within the headlight assembly; not a separate, user-replaceable bulb in many configurations.

Halogen setups are common on XL and some XLT trims. If your truck shows two filaments in the headlamp bulb you’re replacing, you’re likely dealing with H13 halogen units.

LED headlights

• LED headlights: use integrated LED modules within the headlamp assembly rather than replaceable bulbs.


• Notes: If an LED headlight module fails, service typically involves replacing the headlamp assembly or the LED module as a unit rather than swapping a single bulb.

Trims with factory-installed LED headlights will not use traditional bulbs for the headlamp itself; consult Ford’s parts diagrams for replacement options and warranty guidance.

Rear lighting: taillights, brake/turn signals, and reverse

The rear lighting package on the 2018 F-150 varies by trim. Some models keep traditional bulbs, while others move to LED tail lights. The following outlines the common bulb configurations you may find behind the vehicle.

Tail/Brake/Turn lights

• Rear combination lamps: commonly use 3157-series bulbs (two-filament) for the tail and stop/turn functions on models with halogen rear lighting.


• LED rear lighting: on higher trims or with LED packages, rear lights may use LED modules instead of replaceable bulbs.

If your F-150 uses halogen rear lamps, you’re most likely dealing with 3157 bulbs for the tail/stop/turn functions. Check your specific trim to be sure, as configurations can vary with options.

Backup lights and license plate lighting

• Reverse lights: commonly use 921 bulbs (or similar compact, straight-witting wedges on some builds).


• License plate lights: typically small wedge bulbs such as 194 (WWG wedge) in many Ford trucks.

LED tail lamps on certain trims may forego replaceable bulbs for the rear signal and reverse lighting, requiring module or assembly replacement when needed.

Interior and other exterior lighting

Beyond the headlights and tail lights, several interior and exterior courtesy lights use smaller, standard bulbs. The exact type can vary, but many 2018 F-150s rely on compact wedge bulbs for several fixtures.

Interior and auxiliary exterior lights

• Dome and map lights: commonly use 194 wedge bulbs (or similar W2.1x9.5d types) depending on the exact interior trim and fixtures.


• Cargo area lights and glovebox lights: typically the same small wedge bulbs as the dome lights, frequently 194 or similar variants.


• Other courtesy lights: may use 168, W5W, or similar small bulbs depending on the exact location and assembly.

Because interior lighting is highly trim-specific, verify the exact bulb size by checking the bulb itself or the owner’s manual for your configuration.

How to verify the exact bulb types for your truck

Given the variations by trim and optional packages, the most reliable way to confirm bulb types for your 2018 F-150 is to reference the owner’s manual, inspect the existing bulbs, or use a VIN-based parts catalog from Ford’s official resources or a trusted parts retailer. If you’re replacing a bulb yourself, removing the old bulb and noting the part number or size stamped on the base is a quick way to ensure you buy the correct match. For headlamps, check whether your truck has halogen or LED headlights, as that single difference changes whether you replace a bulb or the entire assembly.

Summary

The 2018 Ford F-150 can use several bulb configurations depending on trim and options. Halogen headlights typically use H13 (9008) bulbs, with H11 for fog lights, while LED headlamps use integrated modules. Rear lighting most often relies on 3157 bulbs for tail/turn/brake on halogen builds, with LED rear lighting on higher trims. Backup lights commonly use 921 bulbs, and license plate and interior lights frequently rely on small wedge bulbs such as 194. Because configurations vary, always verify with the owner’s manual or a VIN-based parts lookup to ensure you replace the correct bulb type for your exact truck.

Are both taillight bulbs the same on a 2018 F150?

And typically for these 2018 to 2020 F-150s. The two tail light bulbs are going to be the same. And that's going to be a 3157. Then your reverse light bulb is going to be a 7440.

Do I need H11 or 9005?

H11 bulbs are designed for use as low beam headlights, while 9005 bulbs are typically used for high beams. This results in a higher brightness level for the 9005 bulbs compared to the H11 bulbs.
