2019 Ford Ranger Bulb Size Guide: Headlight, Tail, Fog & More

The 2019 Ford Ranger marked the triumphant return of the midsize pickup to the North American market. Whether you are driving a base XL, an XLT, or the fully-loaded Lariat trim, knowing your exact bulb sizes is crucial when a light burns out or when you're looking to upgrade your nighttime visibility.

As an ASE-certified master technician, I have compiled this comprehensive bulb size guide to help you find the exact replacements you need. Note that the Lariat trim (and some optioned XLTs) come equipped with factory LED lighting for the headlights, fog lights, and taillights, which are sealed units that do not have replaceable bulbs. The sizes below apply primarily to models equipped with halogen housings.

Quick reference

LED vs halogen upgrade considerations

If you have the standard halogen projector (low beam) and reflector (high beam) housings on your 2019 Ranger, upgrading to aftermarket LED bulbs is a very popular modification. However, there are a few important considerations:

• CANBUS Systems and Flickering: The 2019 Ranger uses a smart Body Control Module (BCM) to monitor lighting circuits. If you install an LED bulb that draws significantly less power than the factory halogen, the truck may think the bulb is burnt out. This can cause "hyper-flashing" on turn signals or flickering headlights. To prevent this, make sure to buy LED bulbs with built-in CANBUS decoders, or add inline load resistors.
• Dust Covers: The Ranger's headlight assemblies have tightly fitted dust caps to keep moisture out. Many high-output LED bulbs have large cooling fans or heat sinks on the back. You may need to purchase extended aftermarket dust covers to fit over the new LED bulbs while maintaining a waterproof seal.
• Beam Pattern: The factory halogen low beam uses a projector housing. Ensure your aftermarket H11 LED bulbs have a thin profile and are aligned correctly (usually with the LED chips facing 3 o'clock and 9 o'clock) to prevent blinding oncoming traffic.

How to replace each bulb

Here are a few quick tips for replacing the most common bulbs on your 2019 Ford Ranger:

• Headlights (Low and High Beam): Accessing the headlight bulbs requires going through the front wheel wells. Turn the steering wheel all the way to one side, remove the retaining clips and screws holding the fender liner, and peel the liner back. You will then see the dust caps covering the rear of the headlight assembly. Twist the cap off, unplug the connector, and twist the bulb counterclockwise to remove it.
• Fog Lights: These can be accessed from under the front bumper. There is a small air deflector/splash shield that may need to be slightly flexed or unbolted to give your hand enough clearance to twist the H11 bulb out of the housing.
• Tail, Brake, and Rear Turn Signals: Drop the tailgate and locate the two bolts on the inside lip of the bed near the taillight assembly. Remove these bolts and carefully pull the entire taillight assembly straight back toward you. Once the housing is free, twist the bulb sockets counterclockwise to replace the 3157 bulbs.
• License Plate and Reverse Lights: License plate lights (194/168) twist out easily from under the rear bumper. Reverse lights are located in the taillight assembly and are replaced following the same steps as the brake lights.

Common lighting issues for this generation

The 2019 Ford Ranger is generally reliable, but some owners have reported a few minor lighting quirks:

• Moisture in the Headlights: Some early build 2019 Rangers experienced condensation inside the headlight assemblies. While a light mist that clears up after running the headlights is considered normal by Ford, pooling water requires replacing the entire assembly under warranty or sealing the edges with marine-grade silicone.
• Hyperflashing After Towing: Occasionally, the trailer lighting module can cause the truck's turn signals to hyper-flash even after a trailer is disconnected. A quick reset of the BCM or cycling the ignition usually clears this fault.
• Burnt Out Halogens: Due to the higher voltage output of modern alternators, factory H11 halogens tend to have a shorter lifespan. If you find yourself replacing them yearly, consider upgrading to a high-quality, CANBUS-compliant LED kit.

Whether you're swapping a burnt-out brake light or completely overhauling your Ranger's night vision with LEDs, always double-check your connections and ensure your housings are sealed.
