🚫 Do not drive — Driving without functional brake lights is illegal and extremely dangerous to you and other drivers.
Key Takeaways
  • The brake light switch on a 1955-1956 Studebaker is a hydraulic pressure switch located on the master cylinder, not a mechanical one at the pedal.
  • Failure of this switch is a critical safety issue; if your brake lights don't work or are stuck on, the car should not be driven.
  • New aftermarket parts from brands like Standard Ignition are the only practical and reliable replacement option, as OEM parts are no longer available.
  • Replacement requires bleeding the brake system, so be prepared for this essential step if you plan to do the job yourself.
On your 1955-1956 Studebaker, the brake light switch is a hydraulic pressure switch. Unlike modern cars that use a mechanical switch at the pedal, this part is typically screwed into the master cylinder. When you press the brake pedal, the hydraulic fluid pressure builds up. This pressure activates the switch, which completes an electrical circuit and turns on your rear brake lights. Its function is simple but absolutely critical for safety.

Is Your Studebaker's Brake Light Switch Failing?

For a straightforward part, the symptoms of failure are equally direct. On a classic vehicle like the 1955-1956 Studebaker, problems with the brake light switch are not subtle and present immediate safety concerns.

Key Symptoms of a Bad Brake Light Switch:

  • Brake Lights Do Not Turn On: This is the most common and dangerous symptom. When you press the brake pedal, the switch fails to complete the electrical circuit, and the brake lights do not illuminate. This poses a significant risk of a rear-end collision.
  • Brake Lights Stay On Constantly: The switch can also fail in the 'on' position, causing the brake lights to remain illuminated even when you are not braking. This can confuse other drivers and drain your battery when the car is off.
  • Flickering or Intermittent Brake Lights: As the switch wears out, it can make a poor connection, causing the brake lights to flicker or work unreliably when the pedal is pressed.

Pro Tip: Before condemning the switch, always check the simple things first. Make sure the brake light bulbs are good and check the vehicle's fuse for the brake light circuit.

Choosing the Right Aftermarket Brake Light Switch

For a classic vehicle like a 1955-1956 Studebaker, finding original equipment (OEM) parts is nearly impossible. The good news is that the aftermarket provides reliable, new components that meet or exceed the original specifications. Aftermarket is the standard and only practical choice for this repair.

Available Brands: Standard Ignition

Standard Ignition (also known as Standard Motor Products or SMP) is a long-standing and trusted brand in the automotive aftermarket, known for producing quality electrical components. Their replacement brake light switches are designed as direct-fit parts, ensuring proper installation and function. They are manufactured with quality materials like copper alloy conductors to ensure good electrical performance and durability. For this application, Standard Ignition is a reliable and readily available choice.

Note on Brake Fluid: Some aftermarket switch manufacturers warn against using silicone brake fluid. While many classic car owners use silicone fluid, be aware that it has been known to cause issues with some reproduction hydraulic switches. If you experience repeat failures, this could be a factor to investigate.

Typical Replacement Costs

Replacing the brake light switch on a Studebaker is an inexpensive repair. The part itself is affordable, and labor is minimal for a professional mechanic familiar with classic cars.

Item Estimated Cost
New Aftermarket Switch $15.52
Shop Labor $100 - $180
Total Estimated Cost $115 - $196

Cost estimates are approximate and can vary based on your location and the specific repair shop. Labor is estimated at the shop's minimum charge, as the job typically takes less than an hour.

Frequently Asked Questions (FAQ)

Where is the brake light switch located on a 1955-1956 Studebaker?

The brake light switch is a hydraulic pressure switch, which means it is not located at the brake pedal. You will find it screwed directly into the brake master cylinder under the hood.

Is this a difficult part to replace?

For a DIY mechanic, the switch itself is easy to replace—it simply unscrews. However, because it is part of the hydraulic brake system, replacing it will introduce air into the lines. The brake system will need to be bled afterward, which requires specific knowledge and tools. If you are not comfortable bleeding brakes, it is best to have a professional do the job.

Are there any recalls or service bulletins for this part?

No recalls or Technical Service Bulletins (TSBs) were found for the brake light switch on 1955-1956 Studebaker vehicles in the NHTSA database. Given the vehicle's age, official documentation of this type is not typically available in modern online systems.

What else should I check if my brake lights aren't working?

If a new switch doesn't solve the problem, the issue is likely in the electrical circuit. Check for bad grounds, corroded bulb sockets, or breaks in the wiring between the switch and the tail lights. On a vehicle of this age, wiring issues are common.
