Guide to the 1959 Studebaker 4E14 Brake Light Switch
Understanding the hydraulic brake light switch in your classic Studebaker truck and how to replace it.
- The 1959 Studebaker 4E14 uses a hydraulic pressure switch, not a mechanical one at the pedal.
- Failure is a critical safety issue; symptoms include brake lights not working, staying on, or working only under hard pressure.
- Replacement is simple, but you must bleed the brakes afterward to ensure safety.
- The available aftermarket brand, Standard Ignition, is a reliable choice, but be aware of potential longevity issues with hydraulic switches, especially if using silicone brake fluid.
Is Your Studebaker's Brake Light Switch Failing?
On a classic truck like the 1959 4E14, you won't get a warning light on the dashboard for a faulty brake light switch. The symptoms are straightforward and require a visual check. A failing switch is a major safety hazard, so it's important to recognize the signs.
Pro Tip: Check the Basics First
Before you decide to replace the switch, always check the simple things. Make sure your brake light bulbs aren't burned out and that the fuse is good. Also, inspect the two wires connected to the switch for any obvious damage or loose connections.
Choosing the Right Aftermarket Switch
For a 1959 vehicle, finding a new original equipment (OEM) part from Studebaker is no longer possible. Your options are typically New Old Stock (NOS) parts or new aftermarket reproductions. For a simple and common part like a brake light switch, a new aftermarket part is the most practical and affordable choice.
Standard Ignition (Standard Motor Products) is a widely available and reputable brand for this component. Their hydraulic switches are designed to be reliable replacements for the original. However, it's important to note that some reproduction hydraulic switches have known issues, particularly when used with modern DOT 5 silicone brake fluid, which can cause them to fail prematurely. Many Studebaker owners report that these hydraulic switches can have a limited lifespan. For this reason, some owners choose to modify their trucks to use a more modern and reliable mechanical switch, though this requires custom installation.

Frequently Asked Questions (FAQ)
Where is the brake light switch located on my 1959 Studebaker 4E14?
The brake light switch is a hydraulic pressure switch located outside the driver's cabin. You will find it screwed into the master cylinder or a brake line junction block on the vehicle's frame. It will have two wires connected to it.
Is it difficult to replace the brake light switch myself?
No, for a DIY mechanic with basic tools, this is a relatively easy job. It involves unplugging the two wires, unscrewing the old switch, and screwing the new one in. However, because it is part of the hydraulic brake system, you will need to bleed the brakes after replacement to remove any air that entered the lines. This step is critical for safe brake operation.
My brake lights only work when I press the pedal very hard. Is the switch bad?
Most likely, yes. A common symptom of a failing hydraulic switch is that it requires more and more fluid pressure to activate. If your lights only come on during hard stops, the switch is worn out and should be replaced immediately for safety.
Are there any recalls for the 1959 Studebaker 4E14 brake light switch?
No recalls or Technical Service Bulletins (TSBs) were found for the 1959 Studebaker 4E14 brake light switch in searches of the NHTSA database and other public records. This is common for vehicles of this vintage.
