The 1965 Ford F100 features a comprehensive lighting system with 9 bulb positions. It uses halogen technology with a single 6014 LED dual-filament bulb handling both low and high beams. The F100 has been available from 1961 to 1972, and the 1965 model falls in the mid-generation years.
Can You Put LED Bulbs in a 1965 Ford F100?
Upgrading the 1965 Ford F100 to LED headlights is straightforward since it uses a single 6014 LED dual-filament bulb for both low and high beams. You only need one pair of LED bulbs to upgrade both functions. Look for a 6014 LED LED kit that specifically supports dual-filament operation to ensure both beams work correctly. For the fog lights, a LED Fog Light LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 1965 Ford F100
To remove the headlight bulb, disconnect the wiring harness, then twist the bulb counter-clockwise and pull it straight out of the housing. Older model years like the 1965 F100 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 LED Fog Light fog light socket.

Standard halogen headlights on the 1965 Ford F100 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 61 years old, the original bulbs on your F100 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 1965 Ford F100?
The 6014 low beam bulb on the 1965 Ford F100 is a specific fitment. There are no widely recognized cross-compatible alternatives, so make sure to purchase the exact 6014 size. 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.
