Key Points
Ford F-150 headlight bulbs-also called head-lamps, front-light bulbs, or head-lamp lamps-come in a few common sizes (H13/9008, H11, 9005) depending on the model year. Halogen bulbs make about 1,000-1,500 lumens, while newer LED replacements can reach 6,000 lumens or more for the same truck. Good beam aim and meeting U.S. safety rule FMVSS 108 keep you and other drivers safe. Swapping a bulb is a simple do-it-yourself job with a flat-blade screwdriver and gloves, but you must never touch the glass with bare hands. Many drivers upgrade to LED or adaptive matrix lights for brighter, whiter light and lower power draw, yet state laws may restrict plug-in LED conversions. Regular checks, proper aiming, and quick fuse fixes help your F-150's lights last longer and shine true. (xenonpro.com, iihs.org, ecfr.gov, nhtsa.gov)

LED lamps use roughly half the power of halogens and place less load on the alternator, saving a bit of fuel and cutting CO₂ over the truck's life. (btslighting.com)
Frequently Asked Questions
Q: What head-lamp bulb does my 2018 F-150 use?
A: Most 2015-2020 trucks use an H13 dual-beam bulb for both low and high beams unless they have projector headlights, which switch to H11 low and 9005 high. (xenonpro.com)
Q: How bright is a stock F-150 head-lamp bulb?
A: A typical halogen H13 in your truck makes about 1,200 lumens on low beam. (sealight-led.com)
Q: Are LED replacement bulbs legal on public roads?
A: Federal law regulates the bulb itself, but once installed, legality is set by state rules. Check local code and be sure the kit is properly aimed. (nhtsa.gov)
Q: Do brighter bulbs draw more power?
A: Yes-halogen wattage is fixed, but some high-output bulbs trade life for brightness. LEDs give more light per watt and run cooler. (btslighting.com, superbrightleds.com)
Q: Why do my lights look foggy?
A: A hazed lens or moisture inside the housing scatters light. Clean the lens and replace the seal or vent plug if water keeps returning. (iihs.org)
Q: My right high beam stopped working-what should I check first?
A: Swap in a known-good bulb; if it stays dark, check the dedicated right-side fuse in the battery junction box. (f150forum.com)
Q: How long do halogen bulbs last?
A: Expect 500-1,000 hours of use before dimming starts. Heavy vibration or touching the glass can cut that time. (sealight-led.com)
Q: What color temperature is best?
A: Warm 3,000-4,300 K halogen light cuts through rain and fog, while cool 6,000 K LEDs appear whiter but can create more glare if mis-aimed. (vox.com, bulbfacts.com)
Q: Will lifting my truck affect the beam?
A: Yes-raising the front end tilts the lights upward. Re-aim them after any suspension change. (f150forum.com)
Q: Are adaptive headlights available on the F-150?
A: Higher-trim 2025 models can option matrix LED head-lamps that automatically dim parts of the beam for oncoming traffic. (ford.com)
Q: What safety benefit do good headlights provide?
A: Trucks with "good" head-lamps see about 19 % fewer night-time single-vehicle crashes compared to trucks with poor lights. (iihs.org)
Q: Has Ford recalled any F-150 lighting issues?
A: Yes-a 2022 campaign fixed a park-lamp flicker that didn't meet steady-burn rules. Dealers reprogrammed the body control module. (f150gen14.com)
Q: Can I just change one bulb?
A: You can, but replacing both keeps color and brightness even, giving a balanced beam on the road. (xenonpro.com)
Q: How do I keep from blinding other drivers?
A: Use the built-in adjuster screws to keep the cutoff no higher than the center of the other car's grille at 25 ft, and avoid ultra-blue aftermarket bulbs. (f150forum.com, thesun.co.uk)
By understanding sizes, brightness, rules, and simple maintenance, you can keep your F-150's head-lamp bulbs shining bright and safe for years.
