Is Your Ford LTD's Brake Light Switch Failing?
A bad brake light switch is a common issue on older vehicles like the 1965-1974 Ford LTD. Because it's a mechanical part with internal contacts, it can wear out over time. The symptoms are usually easy to spot and should be addressed immediately for safety.
Common Symptoms of a Bad Switch
- Brake Lights Don't Work: This is the most obvious and dangerous symptom. If you've checked the bulbs and fuses, the switch is the next logical part to inspect.
- Brake Lights Stay On: A switch that is stuck in the 'on' position will keep your brake lights illuminated, even when you're not braking. This can drain your battery and confuse other drivers.
- Intermittent Brake Lights: The lights may flicker or only work when you press the pedal in a certain way. This points to worn internal contacts in the switch.
Safety First
Driving with faulty brake lights is illegal and extremely dangerous. If your brake lights are not working, do not drive the vehicle until it is repaired. A non-functional brake light switch is a critical safety failure.
Choosing the Right Aftermarket Brake Light Switch
For a classic vehicle like the 1965-1974 LTD, finding original Ford (OEM) parts can be difficult and expensive. New aftermarket switches are readily available, affordable, and are typically reliable for this simple application. The technology for this part has not changed much, and quality aftermarket versions are more than adequate.
Two common brands you will find are:
- Standard Ignition (SMP): Often considered a top-tier aftermarket brand, Standard produces parts that meet or exceed original specifications. They are a reliable choice for durability.
- Rostra Powertrain: Rostra is another well-known manufacturer of automotive electronics and switches. They offer direct-fit replacement parts engineered to OE standards and are a solid, cost-effective option.
For a simple, non-computerized part like this on a vintage car, both Standard Ignition and Rostra are excellent choices. The key is to ensure the part is listed as a direct fit for your specific year LTD to avoid installation issues.

The brake light switch is located under the dashboard, mounted to the brake pedal support bracket. You will see it attached to the pedal arm, near the top. It is activated by the movement of the pedal itself.
Can I replace the brake light switch myself?

My brake lights work, but my turn signals don't. Could it be the brake light switch?
