The Ford F-350 Super Duty is built for towing, hauling, and long hours on the road, but its factory halogen lights often fall short. Many owners report dim output, limited road coverage, and premature bulb failure—especially on older models. That’s why LED upgrades have become one of the most popular improvements for the F-350. They deliver brighter illumination, longer lifespan, and more reliable performance under heavy-duty conditions.

If you’re searching for the best LED bulbs for the Ford F-350 Super Duty, this guide will help you choose the right upgrades. As a professional LED automotive lighting brand, SEALIGHT offers multiple series designed for different driving needs, and we’ll walk you through the most popular options here.

How Can I Find the Correct Bulb Sizes for My Ford F‑350 Super Duty?

The F-350 spans more than two decades of production, and bulb sizes vary by model year. Compatibility is the most important factor when choosing new bulbs. To find the correct size, you can check your vehicle’s owner’s manual or look directly at the original bulb’s base (this is the most reliable method).

You can also use online tools like the SEALIGHT Ford F-350 bulb finder, which provides bulb size charts for different F-350 Super Duty model years.

Here are some common examples. Typical F-350 headlight bulb sizes include H11/H8/H9, 9005/HB3, H13/9008, and 9007/HB5.

Fog lights often use H10/9145, while brake, turn signal, and DRL bulbs commonly use 3156/3157 or 7440/7443, depending on the year.

LED reverse lights, for example, are especially helpful for backing trailers at night or maneuvering in dark work zones. LED brake bulbs illuminate faster than halogen, giving drivers behind more time to react.
