For 2015–2023 Ford F-150 models with a compatible factory H10 halogen fog light socket, the Lasfit H10 LED fog light bulb is designed to match the original bulb base, electrical connector and available installation space.
Because fog light configurations may vary by trim, factory lighting package or previous modifications, checking the marking on the original bulb remains the most reliable way to confirm fitment.
What Fog Light Bulb Size Does a 2015–2023 Ford F-150 Use?
Some 2015–2023 Ford F-150 models with factory halogen fog lights use an H10 bulb. When reviewing vehicle fitment charts or replacement bulb listings, you may also see the following bulb numbers:
- H10
- 9145
- 9140
- 9055
These bulb numbers are often grouped within the same LED replacement category because they have similar base designs, connector styles or common fog light applications.
However, a matching vehicle year or bulb reference does not automatically confirm fitment. Before ordering a replacement bulb, verify that:
- The vehicle uses a replaceable halogen fog light bulb.
- The original bulb has an H10-compatible base.
- The electrical connector matches the replacement bulb.
- The bulb can be inserted and locked into the factory housing.
- There is enough space behind the fog light for the LED cooling structure.
Are H10, 9145, 9140 and 9055 the Same Bulb?
H10, 9145, 9140 and 9055 are not necessarily identical as original halogen bulb specifications. However, they are frequently grouped together in aftermarket LED bulb listings because their bases and electrical connections may be compatible with the same replacement design.
A product labeled:
H10 / 9145 / 9140 / 9055 LED Fog Light Bulbs
generally indicates that the replacement bulb is designed to cover these commonly associated bulb references.
Even when the numbers appear in the same compatibility group, check the following before installation:
- Does the replacement base match the original bulb base?
- Are the locking tabs in the correct positions?
- Can the bulb be inserted and fully rotated into place?
- Does the factory plug connect without modification?
- Does the LED body clear the housing and nearby components?
A compatibility chart is useful for narrowing the options, but it should not replace a physical check of the original bulb and fog light housing.
Why Can Ford F-150 Fog Light Bulb Sizes Vary Within the Same Model Year?
A Ford F-150 fog light bulb size is not always determined by the model year alone. Two trucks from the same year may use different fog light systems because of trim level, factory options or previous modifications.
1. Different Trim or Equipment Configurations
Different Ford F-150 trims may use different front bumpers, fog light housings or lighting packages. As a result, two trucks from the same model year may not use the same replaceable bulb.
2. Different Factory Lighting Systems
Some vehicles use replaceable halogen fog light bulbs, while other configurations may use integrated LED fog light assemblies.
An H10 LED replacement bulb is intended for a compatible replaceable halogen socket. It cannot normally replace a light source that is permanently integrated into the fog light assembly.
3. Previous Bumper or Fog Light Modifications
The current bulb may differ from the factory specification if a previous owner replaced or modified any of the following:
- Front bumper
- Fog light housing
- Off-road bumper
- Aftermarket fog light assembly
- Auxiliary lighting kit
4. Factory Package or Production Differences
Lighting components may also vary because of equipment packages, production changes or market-specific configurations.
For this reason, online answers to questions such as “What fog light bulb does a 2018 Ford F-150 use?” should be treated as an initial reference rather than final fitment confirmation.
How to Confirm Whether Your Ford F-150 Uses an H10 Fog Light Bulb
There are four practical ways to confirm the original fog light bulb size.
Method 1: Check the Number on the Original Bulb
Inspecting the original bulb is usually the most direct and reliable method.
After removing the fog light bulb, look for a number printed or molded into the bulb body or base. Common markings may include:
- H10
- 9145
- 9140
- 9055
If the original bulb is clearly marked H10, you can generally look for an LED replacement designed for a compatible H10 socket.
- Turn off the vehicle and all exterior lights.
- Allow the halogen bulb to cool before touching it.
- Do not work on the bulb while it is hot.
- Keep the original bulb in case it is needed later.
Method 2: Check the Owner’s Manual
Some Ford F-150 owner’s manuals list exterior bulb sizes in the lighting or maintenance section.
Useful section names may include:
- Exterior Lighting
- Bulb Replacement
- Fog Lamp
- Maintenance
- Lighting Specifications
The manual may separate bulb information by trim or lighting package, so make sure the listed specification corresponds to the actual equipment on your truck.
Method 3: Inspect the Socket, Plug and Available Space
In addition to checking the bulb number, compare the physical installation points:
- Shape of the bulb base
- Number and location of locking tabs
- Shape of the electrical connector
- Required installation angle
- Space inside and behind the fog light housing
- Clearance around wiring and nearby components
LED bulbs may include an aluminum heat sink, cooling fan or integrated driver. These components can make the rear section different from the original halogen bulb, even when the mounting base is compatible.
Method 4: Use Vehicle and Bulb Photos for Fitment Support
If removing the original bulb is inconvenient, the following information can help with a fitment review:
- Vehicle year
- Trim or equipment package
- Photo of the fog light from the front
- Photo of the rear of the fog light housing
- Photo of the original bulb and connector
- Details about any bumper or fog light modifications
These details are generally more useful than providing the vehicle year alone.
How to Tell Whether the Factory Fog Light Is Halogen or Integrated LED
An H10 LED replacement bulb is intended for a fog light assembly that uses a removable halogen bulb.
Use the following checks to identify the factory light type.
Check Whether the Bulb Can Be Removed Separately
If an individual bulb can be rotated and removed from the rear of the fog light housing, the vehicle likely uses a replaceable bulb design.
Look for a Bulb Number
A replaceable halogen bulb will usually have a specific bulb number on its body or base, such as H10 or 9145.
Check Whether the Light Source Is Built Into the Housing
If there is no removable bulb and the light source is integrated into the complete fog light assembly, the vehicle may use an integrated LED unit.
An integrated LED fog light generally requires replacement of the complete housing rather than installation of a standard H10 replacement bulb.
What Should You Check Before Buying an H10 LED Fog Light Bulb?
After confirming the bulb number, review the physical design and installation requirements of the replacement bulb.
1. Base and Locking Tab Compatibility
The bulb base must fit into the original socket and lock securely into the housing.
A bulb that cannot be fully locked may loosen over time, affect the beam direction or reduce the seal around the installation point.
2. Compact Installation Design
Space behind a fog light housing can be limited. A compact all-in-one design can reduce the need for:
- A separate external driver box
- Additional wiring
- A mounting location for the driver
- Extra clearance behind the housing
3. Adjustable LED Chip Position
The position of the LED chips affects how the original fog light housing distributes the light.
A bulb with an adjustable mounting collar allows the LED chips to be rotated after installation. This can help position the light source closer to the orientation of the original halogen filament.
4. Heat Management
LED bulbs generate heat and require an effective cooling structure. Common heat-management components include:
- Aluminum bulb body
- Active cooling fan
- Integrated temperature management
- Intelligent power control
A stable cooling design helps the bulb maintain normal operation during extended use.
5. Water and Dust Protection
Fog lights are mounted low on the vehicle and may be exposed to:
- Rain
- Road spray
- Dust
- Mud
- Everyday road debris
A replacement bulb should include suitable water- and dust-resistant construction for an exterior lighting position.
How the Lasfit H10 LED Fog Light Fits the 2015–2023 Ford F-150
Lasfit has more than ten years of experience in automotive lighting and has developed fitment guidance across different vehicles, model years, lighting positions and original bulb sizes.
The H10 LA Plus Series LED fog light bulb is intended for compatible 2015–2023 Ford F-150 models equipped with factory H10 halogen fog light sockets.
Its fitment-related design includes:
- Compatible bulb references: H10, 9145, 9140 and 9055
- Bulb base: Designed to match the corresponding factory H10 socket

What Does a 360-Degree Adjustable Mounting Collar Do?
Fog light housings may hold the bulb at different angles. If the LED chips are not positioned correctly, the light distribution may be less consistent than expected.
An adjustable mounting collar allows the LED bulb to be rotated after it is installed. This can help the light source better match the orientation required by the original fog light housing.
Adjusting the bulb position may help:
- Improve consistency between the left and right fog lights
- Reduce irregular light scatter
- Create a more suitable light orientation
- Use the original housing more effectively
After installation, park the vehicle on a level surface facing a wall and compare the light position from both fog lights. If one side appears noticeably different, recheck the bulb seating and chip orientation.
The mounting base may separate from the bulb while the collar is being adjusted. After selecting the correct position, reinstall the bulb and confirm that every component is fully secured.
Is 6000K White Light Suitable for a Ford F-150?
A 6000K LED fog light produces a bright white appearance. Compared with the warmer color of many original halogen bulbs, 6000K white light can provide:
- A more modern front-lighting appearance
- Better color consistency with white LED headlights
- Clearer identification of nearby road edges
- Improved visibility of objects near the front and sides of the truck
Fog light performance does not depend on color temperature or rated lumens alone. The final result is also influenced by:
- Original housing design
- LED chip position
- Bulb installation angle
- Fog light aim
- Weather conditions
- Road surface and reflection
For this reason, bulb fitment, installation position and light distribution should be considered along with brightness specifications.
