Finding the best LED bulbs for 2015–2018 Ford Expedition requires extra attention because this model range covers two vehicle generations. The 2015–2017 models belong to the previous generation, while the redesigned 2018 Expedition introduced more factory LED lighting. A bulb that fits an earlier model may therefore be unsuitable—or not replaceable—on a 2018 vehicle.
This buying guide explains which factory lights accept replacement bulbs and compares the best SEALIGHT LED options by brightness, installation, price and intended use.
2015–2018 Ford Expedition Bulb Size Chart
The 2015–2017 Expedition belongs to the final years of the third generation. Ford offered reflector-style and projector-style halogen headlights across different trims, but both designs use separate low- and high-beam bulbs.
The redesigned 2018 Expedition was available with either halogen or LED headlights and fog lights. Ford also lists LED taillamps for this model year. Use the Ford Expedition bulb size chart together with the original lighting type before selecting a replacement.

Best LED Headlight Bulbs for 2015–2018 Ford Expedition
Halogen-equipped 2015–2018 Ford Expeditions use 9005/HB3 and H11/H9/H8 bulb families. SEALIGHT offers several compatible series. This guide recommends the S7S for maximum brightness, the S2S for balanced performance, and the L2S for an easy, compact fit.
| SEALIGHT series | Recommendation | Best match |
|---|---|---|
| SEALIGHT S7S | Brightest option | Frequent travel on highways, rural roads and poorly lit routes |
| SEALIGHT S2S | Best balanced option | Regular use across city streets, suburban roads and highways |
| SEALIGHT L2S | Best direct-fit option | Buyers who prioritize a compact 1:1-style installation |
SEALIGHT S7S 9005/H11 — Brightest Headlight Option
The S7S is the highest-output SEALIGHT option in this comparison. It is best suited to Expedition owners who frequently travel on rural highways, long routes or roads without continuous street lighting.
The SEALIGHT S7S 9005/H11 LED headlight bulbs include two 9005/HB3 bulbs and two H11/H9/H8 bulbs. The four-bulb set produces 6500K white light and uses active cooling to control heat during extended operation.
Its wireless design places the power supply inside the bulb body, eliminating a separate external driver box. The plug-and-play connections fit compatible factory sockets without cutting or modifying the original wiring.
Choose S7S when maximum output and a complete high- and low-beam replacement are the main priorities.
SEALIGHT S2S 9005/H11 — Best Balanced Headlight Option
The S2S balances output, installation size and price. It suits an Expedition used for regular commuting, family trips and a mix of city and highway travel.
The SEALIGHT S2S 9005/H11 LED headlight contains two 9005/HB3 bulbs and two H11/H9/H8 bulbs. Its internal power supply and compact base reduce the wiring that must be positioned behind the headlight housing.
A thin LED mounting board keeps the light source close to the original halogen filament position. This helps maintain more controlled output inside both reflector and projector housings.
Choose S2S for a clear visibility upgrade without moving to the highest-output series.
SEALIGHT L2S 9005/H11 — Best Direct-Fit Headlight Option
The L2S is designed for buyers who prioritize a compact bulb shape and straightforward installation.
The SEALIGHT L2S 9005/H11 LED headlight bulbs include two 9005/HB3 bulbs and two H11/H9/H8 bulbs. The set produces 6500K white light and uses a non-polar, 1:1-style design with an internal power supply.
With no separate external driver box to secure, the L2S requires less space behind the housing. It is a practical choice for replacing aging halogen bulbs when direct fit matters more than maximum output.
After installing any LED headlight bulb, confirm that both bulbs are fully seated at the same angle. Reflector headlights should produce even light without strong upward scatter, while projector headlights should retain a controlled cutoff.
Best LED Fog Light Bulbs for 2015–2018 Ford Expedition
The 2015–2017 Ford Expedition may have factory LED fog lamps or a serviceable H10/9145/9140 application. The 2018 model may use H11 or H10/9145/9140 bulbs when equipped with replaceable halogen fog lights. Integrated LED fog lamps do not accept replacement bulbs.
SEALIGHT offers several fog light series. The XF3 and Force F1 are the top recommendations in this guide. Choose the XF3 for higher output in an H11 application or the Force F1 for a more affordable H11 or H10/9145 replacement.
SEALIGHT XF3 H11 — Higher-Output Fog Light Option
The SEALIGHT XF3 H11 LED fog light bulbs are designed for compatible 2018 Expedition H11 fog light applications.
The pair produces 12,000 lumens at 60 watts with 6500K white output. An adjustable mounting ring helps position the LED chips inside the housing, while active cooling manages heat.
Choose the XF3 when stronger foreground and roadside lighting is the priority. Check the fog light aim after installation to keep the beam low and controlled.
SEALIGHT Force F1 — Affordable Fog Light Option
The Force F1 is the more affordable option for replacing dim or failed halogen fog light bulbs. Two versions cover the bulb families listed for this Expedition range:
- SEALIGHT Force F1 H11 fog light bulbs for compatible H11/H8/H16 applications
- SEALIGHT Force F1 H10/9145 fog light bulbs for compatible H10/9145/9140 applications
The Force F1 produces 6,000 lumens at 20 watts per pair. Its compact fanless design makes it a practical choice for everyday fog light use without the higher output and active cooling of the XF3.
Other LED Bulbs for 2015–2018 Ford Expedition
The 2015–2018 Ford Expedition may use 3156/3157, 7440/7443 or 912/921/T15 bulbs across its rear lighting positions. Choose the product that matches both the bulb family and light color.
Ford Expedition Brake and Tail Light Bulbs
Brake and tail lights require red output. A shared brake-and-tail position must also maintain a clear difference between its low and high brightness levels.
- 3156/3157: SEALIGHT SLJ3 3157/3156 LED brake and tail light bulbs
- 7440/7443: SEALIGHT SLJ3 7443/7440 LED brake and tail light bulbs
Ford Expedition Turn Signal Bulbs
Use amber bulbs for compatible turn-signal positions that require amber output.

- 7440/7443: SEALIGHT SLJ3 7443/7440 LED turn signal bulbs
If hyperflash or a dashboard warning remains after installation, contact SEALIGHT customer support for a compatible free decoder.
Ford Expedition Backup and Reverse Light Bulbs
Reverse lights require white output. Three product sizes cover the main bulb families listed for this Expedition range.
- 3156/3157: SEALIGHT SLJ3 3157/3156 LED reverse light bulbs
- 7440/7443: SEALIGHT SLJ3 7443/7440 LED reverse light bulbs

2015–2018 Ford Expedition Headlight Bulb Replacement Tips
Replacing the headlight bulbs may require more work than simply reaching behind the housing. Ford’s procedure for the 2015–2017 Expedition calls for removing the headlight assembly, opening the service cap and then disconnecting the bulb.
Before choosing an LED bulb, check the space inside the service cap for the cooling fan, base and wiring. Reinstall the cap securely to keep the housing sealed. For a 2018 Expedition with factory LED headlights, the integrated light source is serviced as part of the assembly rather than replaced with a plug-in bulb.
When replacing serviceable halogen bulbs, changing both sides together helps keep the color and output consistent.
Final Thoughts
The best LED bulbs for 2015–2018 Ford Expedition must match its factory halogen or LED lighting setup. Confirm the lamp type before choosing a replacement. For reliable options, shop the SEALIGHT Ford Expedition LED bulb, with fitment support, eligible free U.S. shipping and a 90-day return period.
