What turn signal does a 2013 Ford F150 take?

The 2013 Ford F-150 uses standard 12-volt turn-signal bulbs: amber front signals located in the headlight assemblies and dual-filament rear signal bulbs. Exact bulb numbers vary by trim and market, so it’s best to verify on your specific vehicle.

Turn signals in the 2013 F-150 are part of the exterior lighting system and are designed as replaceable bulbs rather than a single integrated LED unit on all trims. Front and rear signals use different bulb types, and Ford’s catalogs list multiple variants depending on configuration and region. To get the exact bulb numbers for ordering, consult the owner’s manual, the service manual, or the VIN-specific Ford parts catalog.

Where to find the exact bulb type

Before listing typical locations, note that exact bulb types can vary by trim and market. Use these guidelines to identify yours.

• Front turn signals: amber bulbs located in the outer portion of each headlight assembly. Access can be from the wheel well or by removing the headlight unit, depending on trim.


• Rear turn signals: dual-filament bulbs that also serve as tail lights; these are typically accessed from the rear cargo area or tail-light cluster and can usually be replaced individually.

In summary, the F-150’s front and rear turn signals use standard replaceable bulbs, with exact part numbers that vary by configuration. Verify the correct numbers for your vehicle via the owner’s manual or Ford’s parts catalog for your VIN.

How to verify or replace the bulbs

If you want to confirm the bulb type yourself, follow these practical steps. Note that working around the vehicle’s electrical system requires care and patience.

1. Park on a level surface, set the parking brake, and turn off the ignition. If possible, disconnect the battery before handling electrical components.


2. Access the front turn signal by either turning the front wheel to gain wheel-well access or removing the headlight assembly as outlined in your trim’s service manual.


3. Carefully twist or unclip the bulb socket and pull out the old bulb. Read the imprint on the bulb base to identify the exact part number.


4. Install the replacement bulb of the same type, reseal the housing, and reconnect any wiring harnesses.


5. Test the turn signals (and daytime running lights, if equipped) before finishing the reassembly to ensure proper operation.

Double-check that the bulbs sit firmly in their sockets to prevent moisture ingress or poor contact.
