1958 Studebaker 3E12 Brake Light Switch: A Comprehensive Guide
Keep your classic Studebaker safe and its brake lights reliable with the right replacement switch.
- A faulty brake light switch is a critical safety issue; do not drive if your brake lights are not working.
- Symptoms include brake lights not working, staying on constantly, or flickering.
- For this vehicle, a new aftermarket switch from a brand like Standard Ignition is the most practical and reliable option.
- Replacement is a simple DIY task for most owners, requiring less than 30 minutes and basic tools.
Is Your Studebaker's Brake Light Switch Failing?
On a 1958 Studebaker 3E12, you won't get a warning light on your dashboard if the brake light switch fails. A visual check or someone pointing it out are the most common ways to discover a problem. The symptoms are straightforward and indicate an immediate need for inspection.
Key Failure Symptoms
Before assuming the switch is bad, always check your brake light bulbs and the fuse first. If those are fine, the switch is the next likely culprit.
- Brake Lights Don't Turn On: This is the most serious symptom. The switch has failed internally and no longer completes the electrical circuit when you press the brake pedal.
- Brake Lights Stay On: The switch can get stuck in the 'on' position, which will drain your battery when the truck is parked and confuse drivers behind you.
- Flickering or Intermittent Brake Lights: Worn or corroded internal contacts can cause an inconsistent connection, making the brake lights flicker when you press the pedal or drive over bumps.
Safety First: Driving with a Faulty Switch
Driving with a brake light switch that doesn't work is extremely dangerous and illegal. Other drivers have no way of knowing when you are braking, which can easily lead to a rear-end collision. If your brake lights are not functioning, do not drive the vehicle until it is repaired.
Choosing the Right Aftermarket Switch
For a classic truck like a '58 Studebaker, finding original equipment (OEM) parts from the factory is no longer possible. Your options are generally limited to New Old Stock (NOS) parts or new aftermarket parts.
- New Old Stock (NOS): These are original parts that were never installed but have been in storage for decades. They are often very rare, expensive, and the internal components can degrade over time.
- New Aftermarket: For a simple component like a brake light switch, a new aftermarket part is the most practical and reliable choice. Brands like Standard Ignition produce direct-fit replacements that meet or exceed original specifications. They are readily available, affordable, and made with modern materials for better durability.
Some Studebaker owners with older hydraulic pressure switches choose to convert to a more reliable mechanical switch mounted at the pedal. Your 1958 3E12 likely already uses a mechanical switch, making replacement a straightforward, bolt-in job.

Frequently Asked Questions (FAQ)
Is it difficult to replace the brake light switch myself?
No, this is a very easy job for most DIY mechanics. The switch is located under the dashboard, attached to a bracket near the top of the brake pedal arm. It usually involves disconnecting two wires and unscrewing the switch. The entire job can typically be done in under 30 minutes with basic hand tools.
Where is the brake light switch located on my 1958 Studebaker 3E12?
The brake light switch is located inside the cab, under the dashboard. You will find it mounted on a small bracket near the pivot point of the brake pedal arm. When you press the pedal, the arm moves away from the switch's plunger, activating the lights.
My brake lights are stuck on. Will a new switch fix this?
Most likely, yes. If the switch's internal mechanism fails or the plunger gets stuck, it can remain in the 'on' position, keeping the circuit closed and the lights on. This will drain your battery. Replacing the switch is the correct repair for this issue.
Are there any recalls for the 1958 Studebaker 3E12 brake light switch?
There are no specific recalls or Technical Service Bulletins (TSBs) found in public databases for the brake light switch on this vehicle. This is common for vehicles from this era.
