How to Customize Your Ford Headlights with FORScan (Most Popular Tweaks in 2026)

FORScan can change some lighting settings already built into many Ford vehicles. This is called configuration: you are changing an existing vehicle option, not installing new headlight software.

What you can change depends on the model year, trim, and modules in the vehicle. Treat the examples below as things to look for—not as a promise that every Ford has every option.

What headlight settings can FORScan change?

Ford owners commonly use FORScan to adjust how the lights behave, rather than changing the physical headlight units.

• Headlight delay: how long the lights stay on after you leave the vehicle.
• Automatic high beams: enable, disable, or adjust an available automatic-high-beam option.
• Daytime running lights (DRL): available DRL behaviour, depending on vehicle equipment and local rules.
• Lights-on reminder chime: change an available warning setting.
• Fog-light behaviour: available settings for how fog lights behave with high beams.
• Welcome and puddle lights: available lighting when unlocking or approaching the vehicle.

Where to look in FORScan

Lighting settings are often in the Body Control Module (BCM), although the exact location and wording differ by vehicle. Look for named options such as Headlamp Delay, Auto High Beam, DRL, Fog Lamp, Welcome Light, or Lights On Chime.

If FORScan shows hexadecimal “As-Built” values rather than a named setting, do not change a value by guesswork. Find a vehicle-specific reference that matches your exact year and equipment, or leave it alone.

What you need before changing a setting

• A Windows laptop with FORScan for Windows.
• The appropriate Extended License for the configuration change you intend to make.
• A compatible adapter with stable Ford HS-CAN and MS-CAN communication.
• Stable battery voltage and a backup of the original module configuration.

For a simple explanation of why Windows is needed for this type of job, read Which FORScan adapter do I need?. For hardware choices, see our adapter chooser.

A safe way to make the change

1. Connect FORScan and allow it to identify the vehicle.
2. Save a backup of the original module configuration.
3. Change one named setting only.
4. Write the change and let FORScan complete the process.
5. Cycle the ignition as instructed, then test the result safely.
6. If the result is wrong, restore the backup rather than trying more values.

A few sensible limits

Do not use FORScan to defeat legal lighting requirements or safety features in your area. Do not copy configuration values from a different model year, and do not interrupt the connection while the software is writing to a module.

Once you are comfortable with a small lighting setting, another common configuration change is removing the F-150 double honk. Read our Double Honk guide for the same backup-first approach.
