What Lighting System Does the 2018 Ford Fusion Have?

The 2018 Ford Fusion features an extensive lighting system with 13 bulb positions. It uses halogen technology with H11 LED low beams and H9 LED high beams in a dual-bulb configuration. The Fusion has been available from 2006 to 2019, and the 2018 model falls in the late-generation years.

Can You Put LED Bulbs in a 2018 Ford Fusion?

To upgrade the 2018 Ford Fusion headlights to LED, you will need a H11 LED LED kit for the low beams and a H9 LED LED kit for the high beams. Start with the low beams since they are used most often and have the biggest impact on nighttime visibility. For the fog lights, a H8 LED LED bulb provides a clean white output that pairs well with LED headlights.

How to Replace Bulbs on a 2018 Ford Fusion

The H11 bulb uses a quarter-turn bayonet mount that locks with a short twist. To remove the old bulb, disconnect the wiring harness first, then twist the bulb counter-clockwise and pull it out. On the 2018 Fusion, you will likely encounter rubber dust covers behind the headlight housing. These pull off by hand or unscrew depending on the design. Allow about 15 to 20 minutes per side. When installing the new bulb, avoid touching the glass with bare fingers. Skin oils create hot spots that shorten bulb life. Wear clean gloves or handle the bulb by its plastic base only. The fog lights are accessed from underneath the front bumper. You may need to remove a few plastic clips or screws from the fender liner to reach the H8 LED fog light socket.

How Long Do 2018 Ford Fusion Headlight Bulbs Last?

Standard halogen headlights on the 2018 Ford Fusion have an expected lifespan of 500 to 1,000 hours, which works out to roughly 2 to 3 years of normal use. Signs of a failing halogen bulb include noticeably dimmer output, a yellowish tint compared to the other headlight, or intermittent flickering. At 8 years old, the original bulbs on your Fusion are likely overdue for replacement. Even if they still illuminate, reduced brightness significantly impacts nighttime safety. When one headlight burns out, replace both sides at the same time. Bulbs from the same batch age at similar rates, and mismatched brightness is distracting to oncoming drivers.

What Bulbs Are Compatible with the 2018 Ford Fusion?

The H11 low beam bulb on the 2018 Ford Fusion is cross-compatible with H8, H9, H16 bulbs. These share the same physical base and electrical connection, so they will fit the socket. However, H11 is the recommended size because it is optimized for the wattage and beam pattern designed into your headlight housing. For the high beams, the H9 is interchangeable with H11, H8. Using the wrong bulb size can cause improper beam patterns that reduce your visibility and blind other drivers. It can also cause overheating inside the headlight housing, potentially warping the plastic lens or reflector. Always verify the bulb number before purchasing.

Turn off the vehicle and open the hood. Locate the headlight assembly from behind, remove the dust cover or retaining clip, disconnect the wiring harness, twist the old H11 LED bulb counter-clockwise to remove it, then insert the new bulb and reassemble. The whole process typically takes 10 to 30 minutes per side depending on accessibility.

LED bulbs used off-road or in auxiliary lights are legal everywhere. For on-road headlight use, legality varies by state. Many states allow LED retrofits as long as the beam pattern meets DOT standards. For the best legal compliance, choose a DOT-approved H11 LED LED kit that is designed as a direct replacement and produces a proper cutoff pattern without excessive glare.

A pair of halogen H11 LED bulbs costs $15 to $40, while LED conversion kits run $25 to $60 per pair. If you have a shop do the work, expect an additional $20 to $50 in labor per bulb. Replacing them yourself at home saves the labor cost and usually takes under 30 minutes.

Halogen bulbs produce a warm yellow light (around 3200K), last 500 to 1000 hours, and draw more power. LED bulbs emit a brighter white light (5000-6000K), last 25,000+ hours, and use less energy. LED upgrades for the H11 LED position are available as direct plug-and-play replacements.
