Your Guide to the 1959 Studebaker 4E13 Brake Light Switch
A faulty brake light switch is a critical safety failure; here's what you need to know to fix it.
- The 1959 Studebaker 4E13 uses a hydraulic pressure brake light switch, not a mechanical one by the pedal.
- Failure of this switch is a critical safety issue; do not drive the truck if the brake lights are not working.
- Replacement is a simple DIY task, but you must bleed the brakes afterward to ensure safe operation.
- A new aftermarket switch from a reputable brand like Standard Ignition is the most reliable and cost-effective solution.
Is Your Studebaker's Brake Light Switch Failing?
A bad brake light switch on a classic truck like the 1959 4E13 is a major safety hazard. You will not get a warning light on your dashboard. The only way to know it's failing is to see the symptoms yourself or have another driver point it out. The signs are usually very clear.
Key Failure Symptoms
- Brake Lights Don't Work: This is the most common and dangerous failure. The switch no longer makes an electrical connection when you press the brake pedal.
- Brake Lights Stay On: The switch can get stuck in the 'on' position, which will drain your battery and confuse drivers behind you.
- Lights Only Work With Hard Braking: A dying switch may require very high brake fluid pressure to activate. This means your lights might not come on during gentle stops.
A Critical Safety Note
Do not drive your truck if the brake lights are not working. It is illegal and extremely dangerous for you and others on the road. Get the vehicle repaired immediately.
Choosing the Right Aftermarket Switch
For a 1959 vehicle, finding a new original equipment (OEM) part from Studebaker is not an option. Your realistic choices are a used original part or a new aftermarket part.
- New Aftermarket (Recommended): Brands like Standard Ignition produce new replacement switches that are readily available and affordable. For a simple part like this, a new aftermarket switch is the most reliable and practical choice for a truck that is driven.
- New Old Stock (NOS): These are original, unsold parts. They are very rare, expensive, and may have issues from decades of storage. They are best for museum-quality restorations.
- Used OEM: You might find a used switch at a salvage yard, but it's not recommended. You don't know its history, and it could fail just like your old one.
The primary aftermarket brand available for this part is Standard Ignition (often listed as SMP). It is a well-known manufacturer of quality replacement parts for a huge range of vehicles, including classics. Given the simplicity of the part and the brand's reputation, it is a dependable choice.
Check the Simple Things First
Before you buy a new switch, always check your brake light bulbs and the fuse. A burned-out bulb or a blown fuse is a much easier and cheaper fix. Also, check the wires connected to the switch for any visible damage.

Frequently Asked Questions (FAQ)
Where is the brake light switch on a 1959 Studebaker 4E13?
The brake light switch is a hydraulic pressure switch. It is not located inside the cab by the pedal. You will find it screwed into the master cylinder or a brake line junction block in the engine bay. It will have two wires attached to it.
Is replacing the brake light switch a DIY job?
Yes, this is a good job for a DIY mechanic. It involves unplugging the wires, unscrewing the old switch, and quickly screwing in the new one to minimize brake fluid loss. However, you must bleed the brakes after replacement to remove any air that entered the system. This step is critical for your safety.
Do I need to bleed the brakes after replacing this switch?
Yes, absolutely. Because this is a hydraulic switch that is part of the sealed brake system, you will introduce air into the lines when you change it. Air in the brake lines will cause a soft or spongy pedal and a dangerous loss of braking power. You must bleed the brakes to remove this air before driving the truck.
Are there any recalls for the brake light switch?
No, there are no recalls or technical service bulletins (TSBs) listed with the National Highway Traffic Safety Administration (NHTSA) for this issue on a 1959 Studebaker. This is normal for a vehicle of this age.
