1958 Studebaker 3E6D Brake Light Switch: A Comprehensive Guide
Keep your classic Studebaker truck safe and its brake lights reliable with the right replacement switch.
- A faulty brake light switch is a critical safety failure; replace it immediately if your brake lights are not working correctly.
- For the 1958 3E6D, a new aftermarket hydraulic switch from a brand like Standard Ignition is the most practical and affordable replacement option.
- Always check the brake light bulbs and fuses before assuming the switch has failed.
- Replacement is a simple DIY task that most owners can complete in under 30 minutes with basic tools.
Is Your Studebaker's Brake Light Switch Failing?
A faulty brake light switch on a classic truck like the 1958 Studebaker 3E6D is a serious safety hazard. Unlike modern vehicles, there are no dashboard warning lights to alert you to a problem. The symptoms are straightforward and should be addressed immediately.
Key Failure Symptoms
- Brake Lights Do Not Turn On: This is the most common and dangerous symptom. If you have already checked the bulbs and fuse, the hydraulic switch has likely failed internally and no longer completes the circuit under pressure.
- Brake Lights Stay On: The switch can fail in the 'on' position, causing the brake lights to remain lit even when you are not braking. This will confuse other drivers and drain your truck's battery when parked.
- Flickering or Intermittent Brake Lights: The switch's internal components can wear out, causing an unreliable connection. This might make the lights flicker when you press the pedal or even as you drive.
Safety First: Check Bulbs and Fuses
Before you decide the switch is the problem, always perform two simple checks. First, visually inspect the brake light bulbs to ensure they haven't burned out. Second, check the appropriate fuse to see if it has blown. These are common issues that are much simpler to fix.
Choosing the Right Aftermarket Switch
For a vehicle from the 1950s, finding a new original equipment (OEM) part from Studebaker is not a realistic option. Your choices are typically New Old Stock (NOS), used original parts, or new aftermarket parts.
- New Old Stock (NOS): These are original parts that were never installed. They are very rare, expensive, and may have degraded over decades of storage. They are primarily for collectors aiming for 100% originality.
- Used OEM: Pulled from salvage vehicles, these parts are an option but their remaining lifespan is unknown.
- New Aftermarket: This is the most practical, affordable, and reliable choice for most owners. Aftermarket brands like Standard Ignition produce new switches designed to be direct replacements for the original.
Brand Spotlight: Standard Ignition
Standard Ignition is a well-known manufacturer of aftermarket parts for a vast range of vehicles, including classics like the Studebaker 3E6D. Their parts are designed to meet original specifications for fit and function. The Standard Ignition SLS27 is a hydraulic pressure switch that serves as a direct replacement for the original. While generally considered a reliable choice, it's worth noting that hydraulic pressure switches for classic vehicles, regardless of brand, can sometimes have inconsistent quality due to their design. Always test the switch's operation immediately after installation.
Pro Tip: Converting to a Mechanical Switch
Many Studebaker owners find that the original-style hydraulic pressure switches can be prone to failure or leaking. Some have found success converting to a more modern, reliable mechanical switch that mounts near the brake pedal. This modification eliminates the hydraulic failure point and is often considered a long-term solution, though it requires custom installation.

Frequently Asked Questions (FAQ)
Is it difficult to replace the brake light switch myself?
No, this is a simple job for a DIYer with basic tools. The switch is typically screwed into the master cylinder. You will need to unscrew the old one and quickly install the new one to minimize brake fluid loss. It's a good idea to have a rag handy to catch any drips. The entire job can often be done in under 30 minutes.
Do I need to bleed the brakes after replacing the switch?
If you are quick about swapping the old switch for the new one, you can often avoid introducing enough air into the system to require bleeding. However, if the brake pedal feels spongy after the replacement, you should bleed the brakes to ensure all air is removed from the lines.
Are there any recalls for the 1958 Studebaker 3E6D brake light switch?
No recalls or Technical Service Bulletins (TSBs) are on record with the NHTSA for the brake light switch on this vehicle. This is normal for a vehicle of this age.
My brake lights don't work. Is it definitely the switch?
Not necessarily. Always check the easiest things first: the brake light bulbs and the fuse for the brake light circuit. If both of those are good, the switch is the next most likely cause of the problem.
