The Headlamp Switch – From Serial Number C25000 is an OE-style dash-mounted electrical restoration component designed primarily for Ford trucks, with additional applications across select Ford and Mercury passenger cars. This switch restores factory-correct control of the headlamps, parking lamps, and instrument panel illumination on 1976–1979 Ford F-Series pickups and Broncos built from SN C25000 forward. It is a critical service item for classic truck restoration parts projects where proper electrical function and original configuration are required.
Ford revised electrical systems during mid-production runs, making serial-number-specific fitment especially important. This switch is engineered for late-production wiring layouts used from SN C25000 forward, ensuring compatibility with the correct terminal arrangement and dash mounting profile. Original switches from this era commonly fail due to worn internal contacts, heat cycling, and age-related electrical fatigue, leading to intermittent or inoperative lighting. Replacing the switch restores reliable, factory-style lighting control and preserves the original dash appearance.
Manufactured as an OE-style reproduction, this headlamp switch matches original specifications for shaft length, connector layout, mounting geometry, and electrical function. It installs directly into the factory dash opening and interfaces with original-style wiring harnesses without modification. Accuracy is especially important on F-Series trucks, where the headlamp switch is a frequently used and highly visible control.
In addition to truck applications, this switch also services select 1973–1978 Ford and Mercury passenger cars that are not equipped with hidden headlamp systems, making it a versatile OE-style replacement across multiple platforms—while keeping truck fitment as the primary application.
Offered as X-Parts by Auto Metal Direct, this headlamp switch is a third-party OE-style replacement selected to meet AMD’s standards for fit and application accuracy. X-Parts provide dependable electrical solutions when AMD all-new tooling components are not required, while still supporting factory-correct restorations.
Auto Metal Direct is a team of true car guys with years of experience in sheet metal reproduction, car restoration and paint/body work. We believe that quality is not subjective! Our mission is to provide the best customer experience for the Ford, Mopar and GM classic car markets - both in products and in service.
Our panels are made from proper gauge steel and include all correct-as-original clips, tabs, flanges, bends and seams. Each time a prototype body panel comes off of a new tooling, we test fit it on a car. The marked up prototype is then used to change and improve the tools, and a new prototype is produced. This procedure might be repeated multiple times but, once the part is finally approved, you can be assured of a quality part.
