2019 Ford F150 Headlights: Everything You Need to Know About Replacement, Maintenance, and Upgrades

If you own or are considering a 2019 Ford F150, understanding your vehicle’s headlights is critical to safety, visibility, and compliance with road laws. The 2019 F150’s headlights are more than just functional—they’re a key component of nighttime driving, inclement weather performance, and even resale value. This guide will break down everything you need to know: from identifying the type of headlights your truck uses, troubleshooting common issues, replacing them (whether with OEM or aftermarket parts), maintaining them for longevity, and ensuring they meet legal standards. By the end, you’ll have the knowledge to make informed decisions about your F150’s lighting system.

Understanding Your 2019 F150’s Headlight System: Types and Configurations

The 2019 Ford F150 was available in multiple trims—from the base XL to the luxury Limited—and headlight setups varied slightly by configuration. Most models came standard with halogen headlights, though higher trims (like the Lariat, King Ranch, and Platinum) often included upgraded LED or Xenon (HID) options. It’s important to confirm your specific trim’s headlight type before attempting any work, as components like bulbs, housings, and wiring can differ.

Halogen Headlights (Most Common): Found in XL, XLT, and some mid-trim F150s, halogen bulbs are affordable and widely available. They use a tungsten filament heated by an electric current to produce light. While reliable, halogens have a shorter lifespan (around 500–1,000 hours) compared to LEDs or HIDs and produce more heat, which can reduce efficiency over time.

Xenon (HID) Headlights (Mid-to-High Trims): Available on Lariat and higher trims, HID headlights use xenon gas to create a brighter, whiter light than halogens. They last longer (2,000–3,000 hours) but require a ballast to regulate voltage, making them more complex to install or replace.

LED Headlights (Optional on Higher Trims): The 2019 F150’s top trims (Platinum, Limited) offered factory LED headlights as an upgrade. LEDs are the most efficient option, with lifespans up to 50,000 hours, lower power consumption, and instant full brightness. They also produce a crisp, modern light pattern that improves visibility.

How to Check Your Headlight Type: Open the hood and look at the back of the headlight housing. Halogen bulbs have a twist-lock base (usually PGJ19-2 or H15 style). HID systems will have a larger, rectangular ballast nearby. LEDs will show integrated circuit boards and no visible bulb filament.

Common 2019 F150 Headlight Issues: Diagnosis and Solutions

Even with proper maintenance, headlights can develop problems. Here are the most frequent issues F150 owners report, along with how to diagnose and fix them:

1. Dim or Flickering Lights

Dim headlights are often caused by worn-out bulbs. Halogens lose brightness as their tungsten filament evaporates; HID and LED systems may dim if the ballast (for HID) or driver module (for LED) fails. Flickering can indicate a loose connection, a failing bulb, or a problem with the vehicle’s electrical system (e.g., a corroded ground wire).

What to Do: First, test the bulb by swapping it with the passenger-side bulb (if both are dim, the issue is likely not the bulb). If the problem persists, check the wiring harness for fraying or corrosion—especially near the headlight housing and under the hood where moisture can accumulate. For HID/LED systems, a professional diagnostic tool may be needed to test the ballast or driver.

2. Cloudy or Yellowed Headlight Lenses

Over time, UV exposure and road debris can cause acrylic headlight lenses to oxidize, creating a hazy yellow film that reduces light output. This is common in all F150 trims, regardless of headlight type.

What to Do: Cleaning the lenses with a headlight restoration kit (available at auto parts stores) can remove oxidation. For severe cases, professional polishing or replacing the lens (if possible) may be necessary. Note: Some 2019 F150s have composite headlights (lens and housing as one piece), so replacement may require the entire assembly.

3. Inoperative High Beams

High beams rely on separate bulbs (often H15 or 9005 types in halogen systems) or a separate LED/HID module. If only high beams fail, the issue is usually a burned-out bulb, a faulty high-beam switch, or a broken wire in the stalk controller.

What to Do: Check the high-beam indicator on your dashboard—if it doesn’t light up when you switch, the problem is likely in the switch or wiring. If it does light up but the beams don’t, replace the bulb first. For HID/LED high beams, a blown fuse (located in the under-hood fuse box) is another common culprit.

4. Water Inside the Headlight Housing

Seals around the headlight housing can degrade over time, allowing water to enter. This causes fogging, corrosion of internal components, and reduced light output.

What to Do: Inspect the housing for cracks or gaps in the rubber gaskets. Replacing the gaskets (inexpensive and available online) often fixes the issue. If water has caused internal damage (e.g., corroded bulbs or sockets), the housing may need to be disassembled and cleaned, or replaced entirely.

Replacing 2019 F150 Headlights: OEM vs. Aftermarket Options

When it’s time to replace your F150’s headlights, you have two main choices: original equipment manufacturer (OEM) parts or aftermarket alternatives. Each has pros and cons, so let’s break them down.

OEM Headlights

OEM parts are made by Ford (or its authorized suppliers) to exact specifications. They match the fit, finish, and performance of your truck’s original headlights.

Pros:

• Guaranteed Compatibility: No risk of incorrect fitment, which is critical for proper alignment and beam pattern.
• Warranty Coverage: Ford backs OEM parts with a limited warranty (typically 1–2 years), covering defects in materials or workmanship.
• Consistent Performance: OEM bulbs (e.g., Sylvania or Philips halogens) are engineered to work with your truck’s electrical system, reducing the chance of flickering or premature failure.

Cons:

• Higher Cost: OEM headlights (especially LED or HID assemblies) can cost $300–$800 per pair, plus labor if installed by a dealer.
• Limited Innovation: OEM parts rarely include upgrades like adaptive beam technology (available on newer F150s) or enhanced color temperatures.

Aftermarket Headlights

Aftermarket parts are produced by third-party manufacturers. They range from budget-friendly generic options to premium brands that outperform OEM parts.

Pros:

• Cost-Effective: Generic halogen headlights can cost as little as $50–$100 per pair. Premium aftermarket LEDs (e.g., Morimoto, Diode Dynamics) often cost less than OEM LEDs.
• Wider Selection: Aftermarket options include upgraded bulbs (e.g., high-lumen halogens, plug-and-play LEDs) and custom housings for improved aesthetics or performance.
• Easy Installation: Many aftermarket parts are designed for direct replacement, with plug-and-play connectors that eliminate the need for wiring modifications.

Cons:

• Fitment Issues: Cheap generic parts may not align properly, causing uneven beam patterns or rubbing against the hood. Always check reviews for fitment feedback.
• Quality Variability: Low-end aftermarket bulbs may have shorter lifespans or produce inconsistent light (e.g., flickering at high speeds).
• Potential Legal Problems: Some aftermarket LEDs or HIDs produce light that’s too blue (exceeding SAE color temperature limits) or misaligned, which can fail state inspections or blind other drivers.

Key Considerations When Choosing:

• Trim Level: If your F150 has adaptive cruise control or automatic high beams, aftermarket parts must be compatible with these systems to avoid malfunctions.
• State Laws: Most states regulate headlight height (typically 22–54 inches from the ground) and color temperature (6000K or lower for white light; amber for fog lights). Check your local DMV rules before upgrading.
• Bulb Type: For halogen systems, stick to OEM bulb sizes (H15 for low beams, 9005 for high beams). For LED upgrades, choose “canbus” compatible bulbs to prevent error codes on your dashboard.

Step-by-Step Guide to Replacing 2019 F150 Halogen Headlights

Replacing halogen headlights in your 2019 F150 is a manageable DIY project if you have basic tools. Here’s how to do it safely and correctly:

Tools Needed:

• Socket set (including 8mm and 10mm sockets)
• Phillips-head screwdriver
• Trim removal tool (to avoid scratching the grille)
• New halogen bulbs (H15 for low beams, 9005 for high beams—check your owner’s manual for exact part numbers)

Steps:

1. Park Safely and Let the Truck Cool: Turn off the engine and wait 30 minutes to avoid burning your hands on hot components.
2. Open the Hood and Remove the Grille: Use a trim tool to gently pry the grille clips loose (start from the top corners). The grille is held in place by 8–10 plastic clips—set them aside to reuse.
3. Access the Headlight Housing: Behind the grille, you’ll see the headlight assembly held in place by 3–4 bolts (8mm). Remove these bolts with a socket wrench.
4. Disconnect the Electrical Connector: Twist the bulb socket counterclockwise to release it from the housing. Pull the connector straight off the socket—do not yank on the wires.
5. Remove the Old Bulb: Gently pull the bulb out of the socket. Avoid touching the glass part of the new bulb with your fingers (oil from your skin can cause hot spots and premature failure).
6. Install the New Bulb: Insert the new bulb into the socket, then twist clockwise to lock it in place. Reconnect the electrical connector.
7. Reassemble the Housing and Grille: Put the headlight assembly back into place and tighten the bolts. Reattach the grille clips, starting from the bottom to ensure proper alignment.
8. Test the Lights: Turn on the headlights and high beams to confirm they work. Adjust the aim if necessary (use a wall or garage door to check alignment).

Pro Tip: If you’re replacing both low and high beams, do one at a time to avoid mixing up the bulbs. Take photos during removal to reference the original setup.

Maintaining Your 2019 F150 Headlights for Longevity

Proper maintenance can extend the life of your headlights and keep them performing at their best. Here are actionable tips:

1. Clean Lenses Regularly

Road salt, bug splatter, and dirt can reduce light output by up to 50%. Wash your F150’s headlights weekly with car wash soap and a soft cloth. For deeper cleaning, use a headlight restoration kit (follow the manufacturer’s instructions to avoid scratching the lenses).

2. Inspect Seals and Gaskets

Every 6 months, check the rubber seals around the headlight housing for cracks or brittleness. Replace them immediately if damaged—this prevents water intrusion and corrosion.

3. Rotate Bulbs (Halogen Only)

Halogen bulbs wear unevenly if left in one position for too long. Every 12–18 months, swap the low and high beam bulbs to balance filament wear.

4. Avoid Over-Tightening Bolts

When installing the headlight housing, tighten bolts just enough to secure it—over-tightening can crack the plastic housing, leading to costly repairs.

5. Check Electrical Connections

Corroded or loose connections are a common cause of headlight failure. Use dielectric grease on bulb sockets and wiring terminals to prevent moisture buildup and oxidation.

Legal and Safety Considerations for 2019 F150 Headlights

Your F150’s headlights must meet federal and state regulations to be street-legal. Here’s what you need to know:

• Federal Motor Vehicle Safety Standards (FMVSS): All headlights must produce a white light (color temperature between 4300K and 6000K) with a minimum intensity of 700 candelas on low beams and 2,250 candelas on high beams. Aftermarket parts that don’t meet these standards are illegal.
• State Laws: Some states (e.g., California, Texas) have additional rules. For example, California requires headlights to be aimed so that no part of the high beam illuminates above a 0.5-degree vertical angle. Check your state’s Department of Motor Vehicles (DMV) website for specifics.
• Visibility: Even if your headlights are legal, ensure they’re clean and properly aligned. Misaligned beams can blind oncoming drivers or reduce your ability to see the road.
