FOG LIGHT BULBS
Standard Replacements
Verified Fitment
LED Alternatives
Finding the correct automotive fog light bulbs for your vehicle starts with identifying the exact lighting system installed from the factory. Fog lights can vary by model year, trim level, bumper package, lighting package, and other equipment, even when two vehicles share the same make and model.
ALBulbs helps you narrow down the correct bulb by matching your Year, Make, Model, and Configuration when available. Your results may show the bulb number used for the fog light position along with verification information, fitment notes, standard replacement options, and available LED alternatives.
Before purchasing a replacement, compare the ALBulbs result with the bulb and fog lamp assembly currently installed on your vehicle whenever practical.
What Are Fog Lights?
Fog lights are auxiliary forward-facing lights mounted lower on the vehicle than the primary headlights. They are intended to provide additional illumination close to the road surface, particularly in conditions such as fog, rain, snow, dust, or other situations where visibility is reduced.
Their lower mounting position and beam pattern can help illuminate the roadway without producing the same amount of reflected glare that high-mounted lighting may create in heavy fog.
Fog lights are not intended to replace the vehicle’s normal low-beam headlights. They are an additional lighting system designed for particular driving conditions.
Not every vehicle is equipped with fog lights. Some trims may include them as standard equipment, while others may offer them only as part of an optional package.
Find the Correct Fog Light Bulb for Your Vehicle
The easiest way to identify your fog light bulb is to use the ALBulbs Vehicle Finder.
Select your year, make, model, and available configuration. If ALBulbs has a fog light fitment for that vehicle, the result will be listed under the applicable lighting position.
A vehicle may use a different fog light bulb depending on its bumper design, trim level, production configuration, or factory lighting package. For that reason, avoid purchasing a replacement based only on a broad listing such as “fits all models.”
Common Fog Light Bulb Sizes
Fog lamps can use many of the same bulb families found elsewhere in automotive lighting. Depending on the vehicle, common fog light bulb designations may include:
- H11
- H8
- H16
- 9006
- 9145
- 5202
- PSX24W
- PS24W
These are examples only. The correct bulb depends on the vehicle and the fog lamp assembly installed.
Two bulbs may look similar while using different locking tabs, electrical connectors, wattages, or base designs. Always match the actual bulb number rather than relying on appearance.
For more information about automotive bulb designations, visit the Automotive Bulb Size Guide.
Halogen Fog Light Bulbs
Many factory fog lamps use traditional halogen bulbs. Halogen bulbs produce light from a heated filament and are available in a wide range of automotive bulb sizes.
If your vehicle was designed for a halogen fog light bulb, replacing it with the same bulb number and technology is usually the most straightforward option.
Replacement halogen bulbs may be offered in several versions, including standard output, longer-life, or different color-temperature designs. Regardless of the product variation, the bulb must still match the required base and application.
When installing a halogen bulb, avoid touching the glass capsule with bare fingers. Oils from the skin can contaminate the glass and may reduce bulb life.
LED Fog Light Bulbs
LED replacement bulbs are widely available for many fog light applications. Because fog lamps are auxiliary lights, some drivers choose an LED alternative to change the appearance or light output of the fog lighting system.
However, an LED bulb sharing the same base as the original halogen bulb does not automatically guarantee complete compatibility.
Potential issues can include:
- Limited space behind the fog lamp housing
- Heat sink or cooling fan clearance
- Electrical polarity
- Bulb-out warning systems
- CAN bus compatibility
- Beam pattern changes
- Water-resistant housing clearance
- Different electrical loads
ALBulbs therefore keeps an LED option separate from the original standard fitment. When an LED Alternative is shown, it should be treated as an additional replacement option rather than a change to the original bulb specification.
For more information, visit our LED Compatibility and LED Retrofit Guide pages.
Yellow vs. White Fog Lights
Fog light bulbs and assemblies are available in different color appearances. Traditional fog lamps have sometimes used selective yellow light, while many modern vehicles use white or cool-white fog lighting.
Changing the bulb color does not change the bulb’s physical fitment. A bulb still needs to match the correct base, connector, electrical system, and lamp assembly.
If you are considering a different color temperature or bulb color, review the product specifications carefully and make sure the selected product is appropriate for automotive use.
You should also check applicable laws and regulations in your area before changing the color of exterior vehicle lighting.
Why Some Vehicles Have Multiple Fog Light Configurations
Fog light equipment often varies between trim levels and appearance packages. One version of a vehicle may have conventional replaceable fog light bulbs, while another may use an integrated LED fog lamp assembly.
Some vehicles may have no factory fog lamps at all, even though a higher trim level of the same model includes them.
Bumper changes during a model year can also affect the fog lamp assembly and the bulb used inside it.
This is why configuration-specific information is important. When ALBulbs asks you to select a lighting or vehicle configuration, choose the option that most closely matches the actual equipment on your vehicle.
Factory LED Fog Lamps
Some newer vehicles use integrated LED fog light assemblies instead of traditional removable bulbs.
In these systems, the LED light source may be built into the complete lamp assembly. If the light stops working, there may not be a conventional replaceable bulb behind the lens.
Diagnosis may involve the complete fog lamp assembly, LED module, wiring, control circuit, connector, fuse, or other electrical component.
If your vehicle is identified as using a factory LED fog lamp, inspect the actual assembly before purchasing a bulb that may not be applicable.
Understanding Your Fog Light Fitment Results
ALBulbs may display one of several verification labels with a fog light result.
- Not Verified — The fitment has supporting information, but ALBulbs does not currently have enough qualifying evidence to assign a higher verification level.
- Verified — The fitment has stronger supporting evidence, such as qualifying manufacturer information or confirmation from multiple sources.
- Cross-Checked Verified — The fitment has a higher level of independent supporting confirmation.
A Not Verified result should not automatically be interpreted as incorrect. It means additional confirmation is especially important before ordering the bulb.
Visit Understanding Your Results for a detailed explanation of fitment labels and how ALBulbs handles verification information.
Check the Existing Fog Light Bulb Before Ordering
Whenever possible, inspect the bulb already installed in the fog lamp before purchasing a replacement.
Look for the bulb designation printed or stamped on the base. Compare the connector and mounting tabs with the replacement product you are considering.
This additional check is especially useful when:
- Your vehicle has multiple possible fog light configurations
- Your result is marked Not Verified
- The bumper or fog lamp appears to be aftermarket
- The vehicle has been modified
- You are converting from halogen to an LED alternative
If the installed bulb does not match the ALBulbs result, investigate the difference before ordering or attempting installation.
Aftermarket Fog Light Assemblies
Previous owners sometimes replace damaged fog lamps or install aftermarket fog light kits. An aftermarket assembly may use a different bulb than the original factory equipment.
This can create a situation where a vehicle database correctly identifies the factory bulb, but the physical lamp installed on the vehicle requires something different.
If your fog lamp housing looks different from the original equipment or uses an unfamiliar connector, check the markings on the assembly and installed bulb before ordering a replacement.
Replace Fog Light Bulbs in Pairs?
If one halogen fog light bulb has failed after years of use, the bulb on the opposite side may have accumulated a similar number of operating hours.
Replacing both at the same time can help maintain a more consistent appearance and light output between the left and right fog lamps.
Before ordering a pair, verify that both sides use the same bulb number and that neither side has been replaced with a different aftermarket assembly.
Fog Light Bulb Fitment Matters
A fog light bulb must do more than physically fit into the housing. Its base, connector, electrical requirements, light-source position, and relationship to the reflector or projector can all affect how the lamp performs.
Installing the wrong bulb can result in poor illumination, an improper beam pattern, electrical warnings, loose mounting, or a bulb that cannot be installed correctly.
ALBulbs is designed to bring the vehicle, lighting position, bulb number, fitment evidence, and replacement options together so you can make a more informed decision before purchasing.
