2024 Ford F-150 — Bulb Sizes (Headlight, Tail, Fog)

Quick reference

Notes:

• For 2024, most F-150 trims (XLT and up, plus Raptor/Platinum/King Ranch/Lariat) ship with factory LED headlamps, DRLs, fogs, and LED tail lamps. These use sealed LED boards/modules and do not have individual bulb part numbers. Replacement typically requires the full lamp assembly.
• Some XL and fleet-oriented builds may use halogen headlamps and incandescent tail lamps with replaceable bulbs. Exact bulb numbers can vary by build package. Always verify by checking the owner’s manual, the socket stamping, or your VIN-specific parts catalog.

LED vs halogen upgrade considerations

• Headlamp swaps: Upgrading a halogen-equipped XL to OEM LED headlamps is not a simple bulb change. It generally requires the complete LED headlamp assemblies, compatible harness/adapters, and body control module (BCM) programming to enable proper DRL and high-beam functions. Aftermarket plug-in LED “bulbs” in halogen reflectors are not recommended or legal in many regions and can cause glare and poor beam focus.
• CANBUS/PWM behavior: The F-150 uses BCM monitoring and PWM for various exterior lamps. Replacing incandescent bulbs with LED replacements in halogen-equipped trucks can trigger bulb-out warnings, hyperflash, or flicker. Use CANBUS-ready LEDs or add load resistors/decoder modules where appropriate.
• Heat and fitment: Many aftermarket LED replacements have larger heat sinks. Ensure there’s clearance under dust caps (headlamps) and behind the bumper (fogs). Avoid pinching harnesses.
• Legal and aiming: Any headlamp assembly change requires headlight aiming. Keep DOT/SAE compliance in mind to remain road-legal.

How to replace each bulb

Because most 2024 F-150 lamps are LED modules, many “bulbs” are not serviceable individually. Below are general tips for access and replacement.

• Low/high beam headlamps (LED): Replace the entire headlamp assembly. Remove the radiator cover, loosen the grille fasteners, and remove retaining bolts at the headlamp. Slide the lamp forward, disconnect the harness, and swap. Re-aim after installation.
• Low/high beam (halogen-equipped XL): Access the rear of the headlamp through the engine bay. Remove dust caps, twist the bulb counterclockwise, and disconnect the pigtail. Do not touch halogen glass with bare fingers.
• Fog lights: From underneath or via the wheel-liner, remove screws/clips securing the fog lamp bezel or the lamp itself. LED units are replaced as an assembly; halogen versions allow a simple bulb twist-out.
• DRL: Part of the headlamp assembly (LED); requires headlamp replacement if failed.
• Front turn signal: In LED headlamps, it’s integral (assembly replacement). In halogen headlamps, access from the rear of the housing and twist out the bulb socket.
• Tail/brake/rear turn/tail running: Open the tailgate. Remove the two bed-side screws holding the tail lamp. Pull straight back to release alignment pins. Twist the sockets out for serviceable incandescent bulbs, or replace the full LED tail lamp assembly if equipped.
• Reverse light: Serviced within the tail lamp as above. LED versions are integral; incandescent versions are twist-out bulbs.
• License plate lights: Each lamp unscrews from the tailgate applique/bumper. Disconnect and swap the module (LED) or replace the bulb on serviceable versions.
• Side markers: Integrated into the headlamp/tail lamp. LED versions require assembly replacement; serviceable incandescent versions twist out with the socket.
• Interior dome/map: Many 2024s use LED map/dome modules. Carefully pry the lens, release the module, and replace the assembly. If your truck has incandescent bulbs, remove the lens and swap the festoon or wedge bulb. Always test before snapping the lens back on.

Common lighting issues for this generation

• Moisture/condensation in headlamps or tail lamps, especially after impact or pressure washing. Light fogging can be normal; standing water requires lamp replacement.
• Hyperflash or bulb-out warnings after installing aftermarket LEDs in halogen-equipped trucks; resolved with CANBUS LEDs or resistors and proper wiring.
• DRL or fog light flicker with non-OEM LEDs due to PWM control; use quality, PWM-compatible components.
• Broken headlamp/tail lamp tabs from off-road use or minor bumps—lamps can feel loose or misaligned.
• Corrosion in rear bulb sockets on trucks exposed to road salt (halogen/incandescent tails).
• In-bed/third brake light inoperative due to water intrusion at the CHMSL (center high-mount stop lamp) gasket—inspect and reseal/replace as needed.
