2017 F150 License Plate Light Replacement

The 2017 Ford F-150, a mainstay on American roads, is generally reliable, but like any vehicle, it's susceptible to the occasional gremlin. A common issue, and one often overlooked until illuminated by a law enforcement officer, is a faulty license plate light. Replacing these lights on a 2017 F-150 is a straightforward DIY project, requiring minimal tools and technical expertise. This article will guide you through the process, ensuring your F-150 remains compliant and visible.

Understanding the System

Before diving into the replacement, it's important to understand the 2017 F-150's license plate light system. The system typically utilizes two incandescent or LED bulbs housed within individual light fixtures above the license plate. These fixtures are connected to the vehicle's electrical system via a wiring harness. Failure can stem from several sources: a burnt-out bulb, corroded electrical contacts, a damaged wiring harness, or, in rarer cases, a faulty fuse.

Tools and Materials Required

To successfully complete this repair, you'll need the following:

  • New License Plate Light Bulbs: Refer to your owner's manual or an auto parts retailer to ensure you purchase the correct bulb type. The 2017 F-150 often uses a 194 bulb, but confirming is crucial. LED replacements are a popular upgrade offering longer lifespan and brighter illumination.
  • Screwdriver: A Phillips head screwdriver is typically required to remove the light fixture(s).
  • Optional: Small flathead screwdriver or plastic trim tool: Can assist in prying the light fixture loose, if necessary.
  • Optional: Dielectric grease: To protect electrical contacts from corrosion.
  • Safety Glasses: To protect your eyes from debris.
  • Gloves: To keep your hands clean and protected.

Step-by-Step Replacement Procedure

  1. Safety First: Before beginning any electrical work on your vehicle, ensure the engine is off and the parking brake is engaged. It's also advisable to disconnect the negative battery terminal for added safety. However, this might reset some of your vehicle's settings.
  2. Accessing the Light Fixture: Locate the license plate light fixtures above the license plate. On the 2017 F-150, these are typically small, rectangular housings.
  3. Removing the Fixture: Each fixture is usually secured by one or two Phillips head screws. Use your screwdriver to carefully remove these screws. If the fixture seems stuck after removing the screws, gently pry it loose using a small flathead screwdriver or plastic trim tool. Be careful not to damage the surrounding paint.
  4. Disconnecting the Electrical Connector: Once the fixture is loose, you'll need to disconnect the electrical connector from the bulb socket. This connector usually has a small locking tab that you need to depress before pulling the connector free. Examine the connector for any signs of corrosion or damage.
  5. Removing the Old Bulb: With the fixture and connector separated, you can now remove the old bulb. Incandescent bulbs typically pull straight out of the socket. LED bulbs might have a different retention mechanism, so consult the bulb's packaging for specific instructions.
  6. Installing the New Bulb: Insert the new bulb into the socket, ensuring it is securely seated. If you're using an LED bulb, it's polarity-sensitive. If it doesn't light up after installation, try rotating the bulb 180 degrees in the socket.
  7. Reconnecting the Electrical Connector: Reconnect the electrical connector to the bulb socket, ensuring it clicks into place. Apply a small amount of dielectric grease to the connector terminals to prevent corrosion.
  8. Testing the Light: Before reassembling everything, turn on the vehicle's parking lights or headlights to test the new bulb. If it doesn't light up, double-check the bulb's polarity (if LED), the connector connection, and the fuse.
  9. Reinstalling the Fixture: Once you've confirmed that the new bulb is working, carefully reinstall the light fixture back into its housing. Secure it with the screws you removed earlier.
  10. Repeat for the Other Side: If your F-150 has two license plate lights, repeat the process for the other side.
  11. Final Check: After replacing both bulbs, double-check that both lights are working properly.

Troubleshooting

If the new bulb doesn't illuminate, consider these troubleshooting steps:

  • Check the Fuse: Consult your owner's manual to locate the fuse for the license plate lights. A blown fuse is a common cause of light failure.
  • Inspect the Wiring: Carefully examine the wiring harness for any signs of damage, such as cuts, abrasions, or corrosion.
  • Clean the Contacts: If the electrical contacts in the socket are corroded, clean them with a wire brush or contact cleaner.
  • Test the Voltage: Use a multimeter to test the voltage at the bulb socket. If there's no voltage, there's likely a problem with the wiring or the vehicle's electrical system.

Conclusion

Replacing the license plate lights on a 2017 Ford F-150 is a simple and affordable repair that can be completed in under an hour. By following these steps, you can ensure your vehicle remains compliant with traffic laws and maintains optimal visibility. Remember to always prioritize safety and consult your owner's manual for specific information regarding your vehicle. A properly functioning license plate light not only keeps you legal, but also contributes to overall vehicle safety. Investing a little time and effort in this maintenance task can prevent potential headaches down the road.
