1955-1956 Studebaker E17 Brake Light Switch: A Complete Guide
Keep your classic Studebaker truck safe and legal by ensuring your brake lights function correctly.
- The 1955-56 Studebaker E17 uses a hydraulic pressure switch, not a mechanical one.
- Symptoms of failure are simple: brake lights don't work or they stay on constantly.
- For this classic truck, a quality aftermarket brand like Standard Ignition is the reliable and standard repair choice.
- Replacement is an easy DIY task, but you may need to bleed the brakes afterward.
Symptoms of a Failing Brake Light Switch
On a straightforward classic truck like the Studebaker E17, the signs of a bad brake light switch are usually clear. Because the system is simple, diagnosis is also easy. Before assuming the switch is bad, always check your brake light bulbs and the fuse first.
- Brake Lights Do Not Turn On: This is the most common and dangerous symptom. If you have confirmed the bulbs and fuse are good, the hydraulic switch is the most likely problem. An internal failure can prevent it from completing the electrical circuit.
- Brake Lights Stay On: The switch can also fail in the 'on' position. This will cause the brake lights to remain lit even when you are not braking, which can confuse other drivers and drain your battery when the truck is parked.
- Flickering or Delayed Brake Lights: An intermittent failure inside the switch can cause the lights to flicker, or only come on after heavy brake pedal pressure. This indicates the switch is worn and unreliable.
Choosing the Right Aftermarket Part
For a vehicle from the mid-1950s, finding a "New Old Stock" (NOS) OEM brake light switch is highly unlikely and often impractical. The standard for keeping these classic trucks on the road is to use high-quality aftermarket parts.

Frequently Asked Questions (FAQ)
Where is the brake light switch located on my Studebaker E17?
The brake light switch is a hydraulic pressure switch. You will typically find it screwed into the master cylinder under the hood or on a brake line junction block along the frame. It will have two wire terminals connected to it.
Is this a difficult part to replace myself?
No, this is a very easy job for most DIY mechanics. The process involves unscrewing the old switch and quickly screwing in the new one. The main challenge is to minimize brake fluid loss. It's a good idea to have the new switch ready to go the moment you remove the old one. Basic hand tools are all that is required.
Will I need to bleed my brakes after replacing the switch?
Possibly. If you replace the switch quickly, you may only lose a few drops of fluid and not introduce air into the system. However, if a significant amount of fluid is lost or if the brake pedal feels spongy after the replacement, you will need to bleed the brakes to remove any air that has entered the lines.
Are there any recalls or known issues for the brake light switch?
There are no recalls on file with the NHTSA for the 1955-1956 Studebaker E17, as their database generally begins in 1966. Widespread searches of owner forums and technical service bulletins show no common or recurring factory defect related to the brake light switch for this specific model.
