- Standard Motor Products is a trusted aftermarket brand for this part; New OEM parts are generally not available.
- Verify the correct switch for your specific model year, as there are variations between 1961 and 1973.
Is Your F-100 Headlight Switch Failing?
An old headlight switch can cause frustrating and dangerous problems. Because it controls so many lighting circuits and has an internal breaker, the signs of failure can be confusing. If you notice these issues, it's probably time for a replacement.
Symptoms of a Bad Headlight Switch
- Flickering Headlights: This is the most common sign. The internal circuit breaker in the switch overheats from age and resistance, causing it to trip and reset continuously.
- Dash Lights Don't Work: The rheostat that controls the instrument panel light brightness is a common failure point. You might lose all dash lights, or they may not dim properly.
- Switch is Hot to the Touch: A switch that feels warm or hot after use has too much internal resistance and is a fire hazard.
- Burning Smell: A distinct plastic or electrical burning smell from the dash area when the lights are on is a critical warning sign. Stop using the vehicle if this occurs.
- Partial or Total Light Failure: Headlights might work but tail lights don't, or vice-versa. Sometimes, jiggling the knob can make them work temporarily.
Choosing the Right Aftermarket Switch
For a truck that is 50+ years old, finding a "New Old Stock" (NOS) Ford switch is both difficult and very expensive. The most practical and common solution is a new aftermarket replacement.

Are there any recalls for the 1961-1973 F-100 headlight switch?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls for the headlight switch on these specific models. Recalls for Ford truck lighting systems are for much newer vehicles and different types of switches.
Do I need to buy a new knob and bezel?
Maybe. Most aftermarket switches are sold as the switch body only. You will likely need to reuse your original knob, shaft, and the bezel nut that secures it to the dash. Inspect yours for damage before ordering; replacements are available if needed.
Why do my dash lights and dome light not work?
This is a classic symptom of a failed headlight switch. The internal components that control the dash light dimmer (rheostat) and the dome light function often wear out or get corroded over time. Replacing the switch assembly usually solves this problem.
