What Lighting System Does the 2006 Ford E-350 Super Duty Have?
The 2006 Ford E-350 Super Duty features an extensive lighting system with 13 bulb positions. It uses halogen technology with 9007 LED low beams and 194 high beams in a dual-bulb configuration. The E-350 Super Duty has been available from 2002 to 2019, and the 2006 model falls in the early-generation years.
Can You Put LED Bulbs in a 2006 Ford E-350 Super Duty?
To upgrade the 2006 Ford E-350 Super Duty headlights to LED, you will need a 9007 LED LED kit for the low beams and a 194 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 893 LED LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 2006 Ford E-350 Super Duty
The 9007 bulb uses a twist-lock base with a keyed tab for alignment identical to H13. To remove the old bulb, disconnect the wiring harness first, then twist the bulb counter-clockwise and pull it out. Older model years like the 2006 E-350 Super Duty typically offer easy access to the headlight bulbs from behind the headlight assembly under the hood. Most owners can complete the swap in under 10 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 893 LED fog light socket.

Standard halogen headlights on the 2006 Ford E-350 Super Duty 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 20 years old, the original bulbs on your E-350 Super Duty 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 2006 Ford E-350 Super Duty?
The 9007 low beam bulb on the 2006 Ford E-350 Super Duty is cross-compatible with HB5 bulbs. These share the same physical base and electrical connection, so they will fit the socket. However, 9007 is the recommended size because it is optimized for the wattage and beam pattern designed into your headlight housing. The 9007 is a dual-filament bulb, meaning one bulb contains two separate filaments for low and high beams. This is a different design from single-filament bulbs like H11 or 9005. Make sure any LED replacement is specifically designed for dual-filament operation. 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.
